A new Robert F. Kennedy biopic based on the Evan Thomas biography, His Life, is now on the way at New Regency with superstar Matt Damon attached to star.

The film — which is currently untitled — will span a large portion of Kennedy’s life, including earlier days when all of the attention was on his older brother John F. Kennedy, to his rise up into the spotlight as a top political leader, and straight through to his assassination in 1968.

The movie will be directed by Gary Ross and written by Steven Knight. Ross wrote and directed Pleasantville and Seabiscuit, and also wrote Big, Dave, The Tale of Despereaux, and the upcoming remake of Creature from the Black Lagoon.
