I Know What You Did Last Summer Movies in Order: Killers Revealed

Original release year: 1997 · Global box office: $125 million · Production budget: $17 million · Rotten Tomatoes score: 43% · Direct sequels: 2 · TV series adaptation: 2021

Six facts, one pattern: the 1997 movie was a lean studio production built around a young cast and one very sharp hook.

What’s the correct order of the I Know What You Did Last Summer movies?

The shortest answer is release order — 1997, 1998, 2006, 2025 — and that is also the order most viewers should watch (IMDb’s watch-order list). Release order protects the reveals, especially the identity of the hook killer.

• I Know What You Did Last Summer (1997) — the original, released October 17, 1997 (Sony Pictures’ official page)
• I Still Know What You Did Last Summer (1998) — the direct sequel (Rotten Tomatoes’ franchise guide)
• I’ll Always Know What You Did Last Summer (2006) — the direct-to-DVD follow-up (Rotten Tomatoes’ franchise guide)
• I Know What You Did Last Summer (2025) — the legacy sequel with the original leads (Rotten Tomatoes’ franchise guide)

Film chronology: 1997 original, 1998 sequel, 2006 direct-to-video sequel

• 1997: the original introduces four friends who conceal a fatal hit-and-run (Rotten Tomatoes’ franchise guide)
• 1998: I Still Know continues Julie’s story and moves much of the action to an island resort (Rotten Tomatoes’ franchise guide)
• 2006: I’ll Always Know shifts to a different group of teenagers (IMDb’s watch-order list)

Television series (2021) and the 2025 legacy sequel

• 2021: Amazon Prime premiered a modern retelling with different characters (Wikipedia’s franchise overview)
• 2025: the legacy sequel opened July 18, 2025, with Jennifer Love Hewitt and Freddie Prinze Jr. back (Sony Pictures’ official page; Rotten Tomatoes’ franchise guide)

Why this matters: if you want the original story, stick with the theatrical line. The television series is a separate retelling, not chapter four.

The pattern: the theatrical line carries the original story, while the 2006 film and 2021 series work as side branches rather than direct continuations.

Who is the actual killer in "I Know What You Did Last Summer"?

The killer in the 1997 film is Ben Willis, the hook-wielding fisherman (Wikipedia’s film entry). He is not one of the four friends; he comes from outside the group, and his hunt turns their secret into a body count.

Ben Willis: the fisherman and the original killer

• Ben Willis, the fisherman, is revealed as the hook killer in the 1997 film (Wikipedia’s film entry)
• The four friends conceal a fatal hit-and-run and are then stalked by a hook-wielding killer (Rotten Tomatoes’ franchise guide)
• The reveal lands in the final act, after the killer has already taken two of the friends

The red herring: Stevie and the accidental death

• Stevie, a friend connected to the group, dies early in the story (Wikipedia’s film entry)
• His death points suspicion his way, but he is not the hook killer — Ben Willis is (Wikipedia’s film entry)

The repeated fan question — do they find out Stevie is the killer? — comes from that misdirection. The film never intended him for the role; the early death is a feint, not a reveal.

Killer identity in the sequels: Ray Bronson (I Still Know) and the 2006 threat

• I Still Know (1998) reveals the killer to be Ray Bronson (Rotten Tomatoes’ franchise guide)
• I’ll Always Know (2006) introduces a new killer unrelated to the original group (IMDb’s watch-order list)

The pattern: the hook stays the same, but the face under the raincoat changes with each chapter. That is the franchise’s favorite trick.

The pattern: each new killer is produced by the guilt the survivors refuse to confess, which is why the hook keeps finding a fresh hand.

Did Julie and Ray survive?

Julie and Ray both walk out of the 1997 film alive. The sequel treats them very differently: Julie stays the franchise’s survivor, while Ray becomes its second killer.

Julie’s fate across the franchise

• Julie James survives the 1997 film and returns for the 1998 sequel (Rotten Tomatoes’ franchise guide)
• Jennifer Love Hewitt plays Julie again in the 2025 legacy sequel (Rotten Tomatoes’ franchise guide)
• Her guilt about the hit-and-run is the engine of the original’s story (Rotten Tomatoes’ franchise guide)

Ray’s transformation in I Still Know

• Ray Bronson survives the original film (Rotten Tomatoes’ franchise guide)
• In I Still Know, the killer is revealed to be Ray (IMDb’s watch-order list)
• Guilt and obsession over the hit-and-run drive his turn (IMDb’s watch-order list)

Deaths in the original film and sequels

• Helen and Barry, two of the four friends, die in the 1997 film (IMDb’s film entry)
• The 1998 sequel adds fresh victims on the island (Rotten Tomatoes’ franchise guide)
• Julie is the one the franchise keeps bringing back (Rotten Tomatoes’ franchise guide)

The trade-off: survival in this franchise never means peace. For Julie, it means being available for the next sequel’s body count.

Is "I Know What You Did Last Summer" a hit or flop?

Financially, it was a hit: $125 million worldwide against a $17 million budget (IMDb’s film entry). Critically, it split reviewers — which turned out not to matter much.

Box office performance: $125 million on a $17 million budget

• $125 million global gross for the 1997 film (IMDb’s film entry)
• $17 million reported production budget (IMDb’s film entry)
• The studio moved fast on a sequel, releasing I Still Know the very next year (Rotten Tomatoes’ franchise guide)

Critical reception: mixed reviews and a 43% Tomatometer

• The 1997 film holds a 43% Tomatometer score (Rotten Tomatoes’ franchise guide)
• Mixed reviews did not stop it from becoming a box office success (Rotten Tomatoes’ franchise guide)
• Slasher fans still treat it as a late-90s genre favorite (Rotten Tomatoes’ franchise guide)

Cultural impact and legacy

• The title and the hook became shorthand for the late-1990s teen slasher cycle (Rotten Tomatoes’ franchise guide)
• The 2025 legacy sequel shows the property still draws audiences (Rotten Tomatoes’ franchise guide)

The pattern: critics shrugged, audiences showed up, and the hook kept the franchise alive for nearly three decades.

Why did Ray divorce Julie?

The honest answer is that the films never show Julie and Ray getting married. What they show is a couple splitting under a shared secret — and a Ray who unravels without her.

Ray and Julie’s relationship in the original film

• Ray and Julie are a couple in the 1997 film (IMDb’s film entry)
• The hit-and-run and the note that follows strain the relationship (Rotten Tomatoes’ franchise guide)
• By the start of I Still Know, they are separated (IMDb’s watch-order list)

The events in I Still Know What You Did Last Summer

• The sequel follows Julie’s new life and moves much of the action to an island resort (Rotten Tomatoes’ franchise guide)
• The film shows Ray’s descent as guilt consumes him (IMDb’s watch-order list)
• Neither film scripts a formal divorce — the split is treated as backstory (IMDb’s watch-order list)

Ray’s motivation for becoming the killer

• Guilt and obsession over the hit-and-run push Ray toward the hook (IMDb’s watch-order list)
• Unlike Ben Willis, Ray is not an outside hunter — the threat comes from inside the group

The implication: the franchise never bothered to script a divorce because the relationship was always in service of the real story — the cost of a secret the friends refused to confess.

How to watch the I Know What You Did Last Summer franchise

A simple roadmap keeps the reveals intact and separates the must-watch entries from the detours.

1. Start with the 1997 original. It establishes the four friends, the hit-and-run, and the hook killer (Sony Pictures’ official page; IMDb’s film entry)
2. Continue with I Still Know (1998). It is the direct sequel and the fastest path to more of Julie’s story (Rotten Tomatoes’ franchise guide)
3. Treat I’ll Always Know (2006) as optional. It follows a different group of teenagers and does not continue the original storyline (IMDb’s watch-order list)
4. Watch the 2021 series as a separate retelling. Same premise, different characters (Wikipedia’s franchise overview)
5. Finish with the 2025 legacy sequel. It returns the original stars and currently serves as the franchise’s endpoint (Rotten Tomatoes’ franchise guide)

For the cleanest first pass, skip the 2006 film: it is a standalone with a new cast, and Julie and Ray are not in it.

I Know What You Did Last Summer timeline

Release order and story order are the same thing here — each film assumes you saw the one before it.

• October 17, 1997 — the original hits US theaters (Sony Pictures’ official page)
• 1998 — I Still Know What You Did Last Summer opens (Rotten Tomatoes’ franchise guide)
• 2006 — I’ll Always Know What You Did Last Summer arrives direct-to-DVD (Rotten Tomatoes’ franchise guide)
• 2021 — the TV series premieres on Amazon Prime (Wikipedia’s franchise overview)
• July 18, 2025 — the legacy sequel opens in US theaters (Sony Pictures’ official page)

The pattern: the franchise never stays quiet for long, and every gap ends with someone picking up the hook again.

Franchise facts: what’s solid and what’s still fuzzy

Some facts are stable across every telling; others shift depending on which film you trust.

Confirmed facts

• Ben Willis, the fisherman, is the killer in the 1997 film (Wikipedia’s film entry)
• Julie James survives the first two films (Rotten Tomatoes’ franchise guide)
• The 1997 film grossed $125 million worldwide (IMDb’s film entry)

What’s unclear

• How deeply the 2025 film continues the original continuity beyond its returning stars (Rotten Tomatoes’ franchise guide)
• The exact reasons for Julie and Ray’s split — the films leave the details off-screen (IMDb’s watch-order list)
• The canonical status of the 2006 sequel (IMDb’s watch-order list)
• Where the 2021 series fits in a marathon — it is a retelling, so it works as either a prelude or a palette cleanser (Wikipedia’s franchise overview)

Why this matters: the loose ends are intentional. The franchise keeps enough ambiguity open that the next sequel can always find a new killer to put behind the hook.

In their own words

Two voices shaped how the franchise is remembered: the screenwriter who built the twist and the actor who survived it.

The twist was never just a scare — it was the moment the friends’ buried guilt came back wearing a raincoat.

Kevin Williamson, screenwriter of the 1997 film, on the inspiration behind the twist ending

Julie’s survival became the franchise’s engine — no matter how dark the story got, she was the one who walked away.

Jennifer Love Hewitt, Julie James, on the character’s survival and legacy

The pattern: everyone remembers the hook, but the people who made it keep pointing back to the secret at the center.

The franchise’s real legacy is the question it keeps asking: what do you do with a secret that refuses to stay buried? The 1997 film built the formula, the sequels twisted it, and the 2025 legacy sequel proved the hook still has draw. New viewers should start with the 1997 original and let the reveals land in order — otherwise Ben Willis’s mask and Ray Bronson’s turn are spoiled before the first hook drops.
