‘Girls’ actor Adam Driver joins ‘The F Word’

Daniel Radcliffe, Zoe Kazan star in romantic comedy

Up-and-coming actor Adam Driver, who plays Lena Dunham’s love interest on HBO’s “Girls,” has just signed on to play Daniel Radcliffe’s best friend in Michael Dowse’s romantic comedy “The F Word.”

Canadian shingle No Trace Camping is producing the indie pic penned by “The Samaritan” scribe Elan Mastai, whose script appeared on the 2008 Black List.

Radcliffe and Zoe Kazan star as a pair of twentysomethings who meet at a party and hit it off despite the fact that she has a long-term boyfriend. With the best intentions and a little denial, they decide to confront the challenge of being just friends.

Driver is set to play Radcliffe’s brash, ethically dubious confidant, who helps him navigate his romantic dilemma.

David Gross and Jesse Shapira of No Trace Camping (“Goon”) will produce along with Marc Stephenson and Hartley Gorenstein. Dowse and Jeff Arkuss will exec produce with NHO Entertainment’s Mark Costa and Ford Oelman.

Pic is based on the play “Toothpaste and Cigars” by T.J. Dawe and Michael Rinaldi. Production starts Aug. 15 in Toronto, and additional casting is under way. UTA and Jamie Feldman will handle the sale of U.S. rights.

In addition to garnering critical acclaim for his perf on “Girls,” Driver recently wrapped supporting roles in Steven Spielberg’s “Lincoln” and the Coen brothers’ folk music pic “Inside Llewyn Davis.” Gersh-repped thesp previously appeared in Clint Eastwood’s “J. Edgar.”
