Quickest Time You Bailed Out On a Movie?

A Clockwork Orange, probably for similar reasons, and never attempted to watch it again.

There was only one movie I walked out on, and that was so I could go to the bathroom and possibly blow cookies, but thankfully, they stayed down. It was "Three Kings," and my nausea was due to the camera movement and after seeing all the blood and gore, and then what that one guy's lungs were doing when he got shot, I couldn't take it anymore. Mom went with me because she got sick too, but neither of us really barfed. We calmed down in the bathroom and then waited outside the theater for my dad and brother. So, I think I stayed for about 3/4 of the movie.

Most movies I either see them, or don't see them, and I go out of my way to see if it's worth my while to go to the theater these days, rather than waste money or need brain bleach afterwards.

Raptor (2001) - about 10 minutes as well.
