EXCLUSIVE: Hyde Park International has joined the band with Geezer, coming aboard to sell the comedy starring Green Day singer Billie Joe Armstrong about an ex-punk rocker 10 years into his band’s “indefinite hiatus” and struggling with his adjustment to the real world. Lee Kirk wrote and directed the pic, which co-stars Judy Greer, Selma Blair, Chris Messina and Fred Armisen.

Hyde Park International’s team led by president Eric Christenson is handling overseas sales at the Cannes market, where they are debuting footage for buyers. Gersh is repping North American rights. The pic is currently in postproduction and Process Media’s Tim Perell and Let It Play’s Alex A. Ginzburg and Tony Lee are producers.

The story centers on Armstrong’s Perry, who now works in his family’s hardware store. When his hotshot attorney wife (Blair) and daughter forget his 40th birthday, his brother (Messina) takes pity and gives him the money to throw a huge rockstar blowout in a fancy New York hotel. At the party, Perry’s punk past clashes hilariously with his middle-aged reality as he encounters crazy former bandmates and an old-flame-turned-manager (Greer) who offers him a chance to revive his stalled career.

Hyde Park’s upcoming projects include Broad Green’s Toronto acquisition 99 Homes and Christ The Lord, the adaptation of the Anne Rice novel from Cyrus Nowrasteh that Focus Features will release in the U.S.
