On Saturday at the Toronto Film Festival, those in attendance at the screening of "Slumdog Millionaire" got some unexpected live entertainment in the form of a film critic-on-film critic attack. Shortly after the lights dimmed, a source told the NY Daily News "a man in the audience started yelling 'Don't touch me!' People looked around and shrugged. Ten minutes later the voice yells again, 'I said don't touch me!'

Just as during the first outburst, the audience largely ignored the second. However, a few minuted later "the guy stands up in the darkness and thwacks the guy behind him with a big festival binder. He hit him so hard everybody could hear it. Everyone freaked out and turned around."

The man who perpetrated the attack was none other than New York Post film critic Lou Lumenick, and the person on the receiving end of the giant thwack of the binder was Chicago Sun-Times film critic Roger Ebert.

Ebert has difficulties speaking, having been dealing with throat and thyroid cancer for years now, which likely explains the shoulder tapping. Ebert was simply trying to get Lumenick to move over a little bit as his view was slightly obstructed. Lumenick, who reportedly seemed somewhat surprised when he saw who he hit, never offered up an apology.
