Thats a tough one. I hate to name a movie released so late, but maybe Good Will Hunting? I'm sure theres something earlier.Quoting Irish (view post)
I don't remember the first, but I distinctly remember walking out of Godzilla (1998), Employee of the Month, and Edge of Darkness (only other people in the theater were permitted to bring in a toddler and a baby in a baby carrier). Oh and Twilight.
That episode of Knight Rider where he gets married and his wife gets shot and killed fucked me up as a kid.
