Actor Topher Grace is making fun of his own new movie In Good Company in a blink-and-you'll-miss-him scene in Ocean's Twelve.

The Mona Lisa Smile star appears as himself, dishevelled after trashing a hotel room in Hollywood's Standard, which is owned in the comedy heist movie by Brad Pitt's character Rusty.

And when Pitt suggests his long-haired celebrity guest has fallen on tough times, Grace states he "phoned in" his performance in "the Dennis Quaid movie."

The film Grace is referring to is In Good Company, which opens in America December 29th.
