Acclaimed actor William H Macy was unsure of how to prepare for his latest role in animated movie DOOGAL - because he'd never played a mollusk before. The FARGO star, who voices Brian The Snail in the upcoming film based on cult kids TV show The Magic Roundabout, jokes that he turned to nature for inspiration. He quips, "It's the first snail I've ever played - I turned down a slug once. I wet myself and went through a garden to become at one with a snail." The film also stars Whoopi Goldberg, DAME Judi Dench and SIR Ian McKellen.
