“Mad Men” star Jon Hamm has hopped aboard “Howl,” an upcoming indie feature about the obscenity trial provoked by Allen Ginsberg’s famous poem.
According to Variety, the Golden Globe-winning actor will play Jake Ehrlich, the defence attorney in the trial whose life was also the inspiration for the TV series “Perry Mason.”
As previously reported, James Franco is starring as Ginsberg, while Mary-Louise Parker, David Strathairn, Jeff Daniels, Treat Williams and Alessandro Nivola round out the supporting cast.
The film is currently in production and is expected to open next year.
Hamm, who recently guest-starred on “30 Rock,” will appear later this year opposite Josh Lucas in the thriller “The Boy in the Box.” Meanwhile, “Mad Men” fans can look forward to the premiere of the series’ third season this summer.
