You’ll Know What They Did If You Watch This Movie

“Scream” writer Kevin Williamson takes another stab at the teenage slasher genre with “I Know What You Did Last Summer.” The film pits Jennifer Love Hewit (“Party of Five”) and scream queen beauty Sarah Michelle Gellar (TV’s “Buffy the Vampire Slayer”) against a vengeful longshoreman who hunts them systematically. With enough twists to keep you guessing, this is the right time of year to see this movie.
