The director of O BROTHER, WHERE ART THOU? has admitted the HUMANE SOCIETY was worried about a scene in the film where a cow is hit by a car.

A bemused JOEL COEN eventually had to prove the cow was computer- generated. He explains, "The cow was completely created digitally. The special-effects company studied rodeo films of cows being roped and then dragged down on the ground to see what would happen if it got hit by a car."

He added that a frog squashed by JOHN GOODMAN was not real either. (KW/WNWCAN)
