Barry Levinson (The Natural) will direct the film from a script by Adam Mazer (Empire State), based on the Howard Bryant book, The Last Hero: The Life Story of Henry Aaron, says Variety.
The project is said to cover Aaron's 1970s quest to eclipse Babe Ruth's home run record, which he finally did with his 715th home run in 1974.
Tollin is also the producer, writer and director of the 1995 documentary Hank Aaron: Chasing the Dream, while Mazer and Levinson previously partnered on the Emmy-winning biopic You Don't Know Jack, on the life of Jack Kevorkian, for HBO.
No cast has been identified as yet, so the next immediate task is finding someone to carry the role of Hank. Any ideas on who should star?
