Since that film’s success, he has appeared more regularly in high-profile films. He had roles in two Judd Apatow-produced films: Superbad, as the violent owner of the house where Jonah Hill’s and Michael Cera’s characters attempt to steal alcohol, and Pineapple Express, as one of the main villain’s henchmen. He also appeared in Ridley Scott’s American Gangster as an informant for Russell Crowe’s character. Corrigan was also in the movie The Last Winter, as Motor, a mechanic. In 2009 he was in the Oscar-winning short film The New Tenants. In 2009, Corrigan guested on the science fiction drama Fringe as the mysterious character Sam Weiss. He played the role of Sal against Patton Oswalt in the critically praised independent film Big Fan, written and directed by Robert D. Siegel. He also starred in the 2010 John Landis-produced thriller Some Guy Who Kills People, which was directed by Jack Perez. In 2015, he co-starred with Guy Pearce in Results, the fifth feature film by writer-director Andrew Bujalski. The film had its world premiere at the 2015 Sundance Film Festival and was released theatrically on May 29, 2015, and has an 82% rating on Rotten Tomatoes.
