PARK CITY, UTAH Jan. 26 (UPI) -- Gail Daughtry and the Celebrity Sex Pass, which premiered Sunday at the Sundance Film Festival, is a silly comedy based on the popular relationship myth. A firm commitment to silliness and dirty jokes is comedy gold.

Gail (Zoey Deutch) is engaged to be married to Tom (Michael Cassidy). She learns about the idea of a celebrity sex pass, when each partner picks one famous person with whom they are allowed to cheat, at the hair salon where she works with Otto (Miles Gutierrez-Riley).

When Tom actually sleeps with his, a very self-deprecating celebrity cameo, he encourages Gail to find hers, Jon Hamm. Gail and Otto visit Los Angeles for a hair convention and spend the weekend trying to find Hamm.

Director David Wain and co-writers Wain and Ken Marino's style is known to fans of Wet Hot American Summer, They Came Together and their sketch comedy shows. It's not even one specific style like Naked Gun's Zucker/Abrahams/Zucker or Monty Python. It's every form of absurdity and satire.

Gail's small town of Wilbur, Kansas, is quaint to the extreme, with Deutsch amping up her innocent, friendly smile. The film mocks the device of narration, as mailman Frank (Fred Melamed) gives irrelevant information, yet repeatedly chastises viewers harshly.
