I Know What You Did Last Summer Collection

I Know What You Did Last Summer is a 1997 American slasher film based on the 1973 novel of the same name by Lois Duncan. The film stars Jennifer Love Hewitt, Sarah Michelle Gellar, Ryan Phillippe and Freddie Prinze Jr., with Anne Heche and Bridgette Wilson appearing in supporting roles. It centers on four friends who are being stalked by a killer, one year after covering up a car accident in which they were involved. The film was directed by Jim Gillespie, from a screenplay written by Kevin Williamson, writer of Scream. The film was followed by three sequels, I Still Know What You Did Last Summer (1998), the straight-to-DVD release I'll Always Know What You Did Last Summer (2006), and the legacy sequel also titled I Know What You Did Last Summer (2025).

    ★ 6/10

    Ben the Bream. Kevin Williamson, hot off of the success of his screenplay for Wes Craven's Scream, here adapted the Lois Duncan novel with mixed results. A bunch of pretty teenagers in a coastal fishing town run over a man in the road and try to cover it up. Not a wise move at the best of times, even more so now as the victim, a hook wielding fisherman, is coming to get them. And that's pretty much it. Williamson adds some humour into the play, while director Jim Gillespie plays his shock tactics well and keeps the pretty young cast annoying enough for us to want to see the fisherman guy enact revenge. It sadly gets away from itself in the last quarter once the stalker is revealed, and in truth there's very little imagination gone into the whole pic. But it's a decent night in with beer and popcorn for those after a short sharp shock type horror. 6/10

    The guilt will haunt you and maybe even KILL you Released in 1997, "I Know What You Did Last Summer" takes place in coastal North Carolina where a group of just-graduated teens experience a tragic event and compound it by foolishly reacting. They swear to carry the secret to their graves, but the next summer it becomes clear that someone knows their secret and murders start piling up. The teens are played by Sarah Michelle Gellar, Jennifer Love Hewitt, Ryan Phillippe and Freddie Prinze Jr. Also on hand are Johnny Galecki, Anne Heche and Muse Watson. This movie is full of slasher clichés, like the killer who's always in the same garb (this time a fisherman's slicker outfit), the slow-methodical walking of the killer (never running) and the undead dead. There are also two blatant "Yeah, right" scenes (noted below). Thankfully, it makes up for it by the stellar coastal locations (strangely shot on BOTH East and West coasts), a quality cast, some effective sequences and the potent moral on haunting guilt that slowly kills ya. The immediate aftermath of the opening accident is particularly well done. The film runs 99 minutes and shot in Southport, North Carolina, and Jenner, California, and nearby regions of both coasts. GRADE: B or B- (6.5/10 Stars) SPOILER ALERT (DON'T READ FURTHER IF YOU HAVEN'T SEEN THE FILM) Here are the two eye-rolling scenes: 1. The sequence where Max's corpse is found in the trunk with the crabs. It couldn't have been an illusion since Helen didn't yet know Max was dead, so it must've really happened. If so, how would the slicker-killer get the trunk cleaned-up so quickly with no one seeing him in a neighborhood in broad daylight? Also, how did he even get into trunk? Did he have his own personal key? The sequence is just too far-fetched. 2. After Barry is murdered by the killer at the pageant how does he know that the cop and Helen would be driving down the alley by-pass an hour or so later? (I realize the street was blocked off and he might've been the one who set it up, but how did he know this would be the precise route taken by the cop and Helen? And how would he even know Helen would be riding with the cop? It's not like she wouldn't have other friends & family in town with whom she could ride. Anyway, wouldn't people living in the downtown area or other passersby notice a man in full-slicker garb working on his truck? Sequences like these take intelligent viewers right out of the story, which explains Roger Ebert's response: "After the screening was over and the lights went up, I observed a couple of my colleagues in deep and earnest conversation, trying to resolve twists in the plot. They were applying more thought to the movie than the makers did."

    I liked this movie. I wish there was more action and killing but overall pretty good. Has a good cast in it too.
