I've never seen that happen since. You'll hear a movie audience laugh, scream, go "awwww!, or go "eugh!", but rarely cheering and booing. Odd, because people do that at hockey games and such.
Heh. FWIW, I remember hearing people cheer when Obi-Wan cut Darth Maul in half. Of course, I was at Mann's Chinese Theater. Then again, I was in Switzerland when I saw Attack of the Clones and people went
nuts when Yoda busted out his light saber.
Can't remember anyone booing in general for
any movie, though. Interesting...
