In one of those quirks of Hollywood history, Kevin Williamson wrote I Know What You Did Last Summer before he wrote Scream, but Scream got made first.
Unfortunately I Know What You Did Last Summer is essentially the movie Scream was deconstructing and mocking.
Scream had Party of Five’s Neve Campbell; I Know What You Did Last Summer upped it by casting her Party of Five co-star Jennifer Love Hewitt and adding Buffy the Vampire Slayer’s Sarah Michelle Gellar.
That movie, of course, is Scream, which in turn owes its existence to previous, (sometimes-but-not-always) superior movies — and many of those movies are a whole lot like I Know What You Did Last Summer.
