Robin Williams may be the best part of “Absolutely Anything”, a new comedy starring Simon Pegg as a man given the ability to do whatever the heck he wants, TheWrap reports.

In the first trailer, Pegg gives his dog, Dennis, the ability to speak. Williams, who died last year, lent his voice for the part.

“Biscuits! Biscuits! Please! Please! Please! Nothing else matters,” Williams blurts out. “Come to think of it, I wouldn’t mind shagging your leg right now.”

The movie’s premise is reminiscent of “Bruce Almighty,” in which Jim Carrey was given the power of God. In this fall release, however, a group of eccentric aliens voiced by the Monty Python gang (John Cleese, Michael Palin, Eric Idle, Terry Gilliam and Terry Jones, who also directed) decide to enable Pegg to do absolutely anything as an experiment to see whether or not planet Earth should be destroyed.

Much like Carrey, Pegg doesn’t really know what to do with his power, until inevitably coming to his senses to save the Earth in the third act.

Kate Beckinsale, Rob Riggle and Eddie Izzard co-star in the comedy hitting U.K. theaters on Aug. 14, while a U.S. release date has not yet been announced.
