NTSF:SD:SUV::, in which he played Sam Stern. In 2011, Starr had a major role in the film 
A Good Old Fashioned Orgy and also had guest appearances on television series such as 
Mad Love, 
Community, and

Party Down. Starr reunited with 
Freaks and Geeks and

Save the Date, which premiered at the Sundance Film Festival.
