The twice-Oscar-nominated Jeremy Renner continues his pursuit of the manliest film roles possible. Having previously portrayed an armed-forces bomb expert, a Bostonian thug, a superhero who uses a bow and arrow, an IMF agent, Jeffrey Dahmer, and Hansel (of Hansel and Gretel), Renner now takes on the role of Rocky Marciano, the second-most famous boxer named Rocky. Marciano held the title from 1952 to 1956 and remains the only heavyweight champ to retire undefeated, at 49-0. He died in a plane crash in 1969. Undefeated: The Rocky Marciano Story, written by Samuel Franco and Evan Kilgore, is still looking for a director. Hey, what’s Sylvester Stallone doing? He hasn’t directed a boxing movie in a while.
