Director Michael Bay hired the big guns Dwayne "The Rock" Johnson and Mark Wahlberg for his new film Pain & Gain -- and the new poster shows just how pumped these actors got for the roles.

The film, based on a true story, is about a pair of bodybuilders in Florida who get caught up in an extortion ring and a kidnapping scheme that goes terribly wrong. The poster shows Wahlberg and Johnson in tight, muscle-baring tank-tops with an American flag in the backdrop. The tagline for the film reads: "Their American dream is bigger than yours."
