"I thought black people couldn't ski. Or is that swimming?" clueless Irish cop Brendan Gleeson asks Don Cheadle in the first trailer for the comedy 'The Guard.'

Gleeson's less-than-scrupulous small-town police sergeant, who's more likely to participate in vice than stop it, is paired with Cheadle's American FBI agent in the culture-clash comedy. The two lawmen are forced to pair up to stop an international drug smuggling ring.

The movie has already drawn raves at various festivals, including Sundance, Tribeca and Berlin.

Mark Strong and Liam Cunningham ('Dog Soldiers') co-star in the film, which opens in limited release on July 29.
