Actress Kate Bosworth may star in a new film about winning millions in top Las Vegas casinos - but she insists she is not a fan of gambling. The 21 actress plays a college student who cheats her way to winning big in Sin City but the star is adamant she would never fritter away her earnings on a Roulette wheel. Bosworth tells New York Daily News, "I'm all or nothing, within a safe boundary. I'll play blackjack, with a $25 (GBP12.50) chip, for however long it lasts. I don't bet big." However, Ben Mezrich, who is the author of Bringing Down the House - the basis for 21 - is keener to put down large sums of money on a card game. He says, "I'm not that big a gambler. You know, only $20,000 (GBP10,000) here or $30,000 (GBP15,000) there. I know how to count cards, but I couldn't walk in and take a casino right now."
