Matt Damon is attached to a film about the life of Senator Robert F. Kennedy.

Deadline Hollywood is reporting that Damon will look at a script by Dirty Pretty Things and Eastern Promises writer, Steven Knight, before making up his mind. Gary Ross, director of Pleasantville and Seabiscuit, will helm.

Deadline says the film will be based on the Evan Thomas biography His Life and will trace RFK’s transformation from the younger brother in the shadow of President John F Kennedy to a national leader in his own right, before he too was gunned down in 1968.

The assassination at the Ambassador Hotel was the backdrop for Bobby, written and directed by Emilio Estevez. The 2006 movie is a fictionalized account of the hours leading up to the shooting. And Deadline mentions that a film is being developed about RFK’s presidential run, titled The Last Campaign – presumably based on the Thurston Clark book of the same name.

Matt Damon recently played South African rugby star Francois Pienaar in Invictus and will soon be seen in The Green Zone. He has several other projects in development and is, with Ben Affleck, reportedly in negotiations for a first look producing deal at Warners

Knight has been hired by Columbia Pictures to adapt the Dan Brown novel The Lost Symbol.
