Damon, Affleck in Vegas for charity poker tourney

The Ante Up for Africa poker tourney last week at the Rio Hotel in Las Vegas attracted two of the brightest 1,000-watt smiles in Tinseltown, Matt Damon and Ben Affleck.

The longtime friends, who had just returned from a shared vacation in Hawaii, dropped a few large bills at the game, which benefits charities that aid survivors of the horror in Darfur.

Ironically, Damon, who played a geeky genius card sharp kid in "Rounders," was knocked out of the tourney within five minutes. Affleck did much better. But when asked about his old reputation as a big-time gambler, he said: "I've got a kid (Violet), and I'm directing movies. I have hardly any time now."
