Tales from the Gangster Squad is starting to heat up at Warner Bros., with the studio offering Sean Penn the role of Los Angeles mobster Mickey Cohen.

Mickey Cohen was a former boxer who became an associate of Meyer Lansky and Bugsy Siegel. He was a man about Los Angeles, and also a suspected sociopath who caused a great deal of harm to those he came in contact with.

Ryan Gosling has been offered the role of a cop trying to bring this notorious gangster down. Ruben Fleischer is set to direct Tales from the Gangster Squad sometime later this year.

Warner Bros. is also moving forward on the Al Capone biopic Cicero, which looks at the gangster's earlier years. The studio is now wanting Harry Potter and the Deathly Hallows - Part 2 director David Yates to helm the screenplay, which was written by Walon Green. No offer has been made by the studio at this time.
