Pic stars William Forsythe, Penelope Ann Miller and Joe Mantegna and will be directed by Martin Guigui.
Film is a combo prequel-sequel to the Martin Scorsese pic chronicling the life of boxer Jake LaMotta before he became a champ and after his fall. Leachman will play Miller’s mother.
Scott Reed, Joe Allegro, Ron Singer and Dahlia Waingort are producing the pic through Sunset Pictures.
Leachman can be seen next in the CBS Films pic “Gambit” with Colin Firth and Cameron Diaz. She is repped by Innovative Artists.
