Armstrong will play a washed-up punk musician who has difficulty adjusting to the normal world when his band goes on an indefinite hiatus.
The movie co-stars an impressive comedic cast including Judy Greer, Selma Blair, Chris Messina, and Fred Armisen, and apparently the film just got sold at Cannes.
The movie is also promised to include new music written and performed by Armstrong.
This isn’t the first time the punk rocker has been bitten by the acting bug. He’s also appeared on Broadway when the ‘American Idiot’ musical was in production – but this will be the first time the singer takes on a leading role in a film.
