8. Bradley Cooper: Rocket Raccoon

The Guardians of the Galaxy may have been the surprise hit of the last few years, but Rocket Raccoon made the headlines. The furry little rodent with the really big gun made quite an impression on moviegoers, and the voice that drove his madness to purpose was provided by Bradley Cooper.

The star of Silver Linings Playbook certainly unleashed his inner beast in his portrayal of the smart mouthed and surprisingly heroic pilot and adventurer. Chris Pratt did a good job of playing the semi-serious “Star Lord” but the comic relief was regularly delivered by Cooper through brash one-liners.

This casting was great because Cooper has such an electric personality. When he decides to play a role over-the-top, like he did in Silver Linings Playbook, great things are bound to happen. This was no exception.
