There are few more comedic pairs than the Rock and Kevin Hart, which is what makes this summer blockbuster so hilarious. Our CIA comedy begins with a flashback to a once-heavy Bob (Johnson) being bullied in high school and then saved by Calvin (Hart), the school's star athlete. Twenty years later, Bob has hardened into the hunk of man muscle we all now know and love as a CIA agent and needs Calvin's accounting help. We get plenty of shots of the Rock with his shirt off, but the butt is a body double (Sione Kelepi). Either way, that's one tight ass!
