Safe House Pictures and Filbert Steps Prods. are co-producing “Trumbo,” a documentary on blacklisted screenwriter Dalton Trumbo based on a stage play.

Joan Allen, Michael Douglas, Paul Giamatti, Danny Glover, Nathan Lane, Liam Neeson, David Strathairn and Donald Sutherland will recite letters written by the scribe about his banishment, his politics and his experiences on films like “Spartacus,” “Exodus” and “Roman Holiday.”

Kirk Douglas, Walter Bernstein and Victor Navasky will be interviewed.

Safe House’s Will Battersby and Tory Tunnell are producing along with Alan Klingenstein, David Viola and Jim Kohlberg of Filbert Steps, which put up the financing. Producers of the doc, which just began production, will donate a percentage of profits to the ACLU.

Askin previously co-wrote and directed “Company Man” for Paramount Classics and directed an HBO broadcast of John Leguizamo’s one-man show “Spic-O-Rama.”
