The cast for “Howl” is growing, as David Strathairn, Alan Alda, Jeff Daniels, Mary-Louise Parker and Paul Rudd are in talks to join the upcoming Allen Ginsberg biopic, according to The Hollywood Reporter.

Written and directed by Rob Epstein and Jeffrey Friedman, the film focuses on the trail launched to censor Ginsberg’s lengthy poem entitled “Howl.” James Franco is on board to portray the lead character.

Strathairn stars as prosecuting attorney Ralph McIntosh, while Alda plays Judge Clayton Horn. Daniels takes on the role of prosecution witness professor David Kirk, with Parker playing prosecution witness Gail Potter and Rudd starring as defense witness Luther Nichols.

Strathairn was last seen in “The Spiderwick Chronicles” and recently completed “The Uninvited.” Alda will next star in “Flash of Genius,” while Rudd can next be seen in “Role Models.”

As for Parker, she is currently starring in television’s “Weeds.” Daniels can be seen on the big screen alongside Don Cheadle in “Traitor.”   

I haven’t had a chance yet to read through Ginsberg’s poem, but this project sounds pretty interesting. Considering this impressive casting announcement, this is definitely one to look out for once it’s in the can.
