Russell Crowe
Errol Flynn who? The Gladiator star gets down and dirty for director Ridley Scott’s epic retelling of the bandit who stole from the rich and gave to the poor, Robin Hood.

Bradley Cooper
The Hangover star lends his boyish good looks – and hot bod! – to the role of Templeton “Faceman” Peck in the action-packed remake of the ’80s TV sensation The A-Team.
