HBO is developing a movie about Norman Mailer’s relationship with imprisoned murderer Jack Abbott, who assisted the author with the 1980 Pulitzer-winning nonfiction work The Executioner’s Song. Abbott in turn received Mailer’s support for his own book, In the Belly of the Beast, as well as an ill-fated parole that resulted in another murder. Stephen Schiff (Wall Street: Money Never Sleeps) will script the film and Tina Brown will executive produce — a first for the Daily Beast and Newsweek editor.
