rounders - AA999 v. AAA99

[Cincy_Kid_ES]

So I just saw Rounders for the first time ever. I saw the hand where Matt Damon lost his whole bankroll against the Russian KGB guy with AA999 against AAA99. For those of you who have seen the movie, what do you think of Matt Damon's play of moving all in after he thinks the KGB hit his flush on the river and bet out. Would you have just called or would you have moved all in thinking it was nearly impossible he had AA?
