Movie Info

Kevin Williamson scripted this thriller, an adaptation of Lois Duncan's novel about four teens involved in a hit-and-run incident. High school senior Julie is driving with friends when their car hits a fisherman. Assuming he's dead, they throw him in the water. Later they panic after an anonymous note arrives. It simply says, "I know what you did last summer." (In Duncan's book, the teens hit a small boy on a bicycle instead of a fisherman.)

Wastes more opportunities than it does teenagers.

March 28, 2019 | Rating: 2/4 | Full Review…

A dreadful mad slasher film that works neither as a thriller nor as a comic commentary on the genre.

March 28, 2019 | Rating: 1/4 | Full Review…

A poorly conceived 1997 thriller with plenty of empty references.

March 28, 2019 | Full Review…

Tthe frights come fairly regularly, and though the picture neither haunts nor tickles you the way Scream did, it's diverting enough as mindless Saturday-night entertainment.

March 27, 2019 | Rating: 3/5

I Know What You Did Last Summer is gory enough for the devotees and has story enough for everyone else.

March 27, 2019 | Rating: 3/4 | Full Review…

It doesn't live up to the hype it's received, but I Know What You Did Last Summer is still the best Halloween scare out there right now.

Audience Reviews for I Know What You Did Last Summer

½

Kevin Williamson, the same guy who wrote the witty screenplay of Scream making fun of the clichés of horror movies and slashers, also wrote this one here but embracing all those dumb clichés instead; still, at least Gillespie is able to make it suspenseful and relatively fun.

Yawn. So there's a group of teenagers, they kill someone, that someone comes back ... are you bored yet? Yeah me to. The classic mix of screaming beauties, testosterone riddled jocks and slightly outcast plain people running around convincing themselves that anything they do for the 90 minutes this movie lasts matters in the slightest to anyone. One of my least favorite movies ever, and certainly not what one would deem "horror".
