Cinematical has just received this exclusive clip from the upcoming film Choke, based on one of my personal favorite Chuck Palahniuk (Fight Club) books. Choke stars Sam Rockwell as Victor Mancini, a snarky sex addict who cons well-to-do folks out of their money by fake-choking in restaurants while subsequently feeding off the sympathy of others. He then uses this money to help pay his mother's (Anjelica Huston) mental hospital bills. In the clip above -- which is one of a few flashbacks in the film -- young Victor and his mother visit the zoo ... at night ... and they're not exactly there to buy cotton candy. You can learn more about Choke over at its official website. I saw the film back at Sundance and liked it quite a bit -- especially Rockwell's off-the-charts performance as Mancini. Definitely see this one when you get the chance; it arrives in theaters on September 26. Additionally, watch the trailer and another clip over on Moviefone. Enjoy.
