Guardians of the Galaxy
Chris Pratt is quite the goofball on set, but that can definitely work well for his character, Star-Lord, from Guardians of the Galaxy. In one scene, he is supposed to hold up the orb but accidentally dropped it. Thankfully, he didn't get out of character so the scene could still be used in the final cut. Directors loved the carefree attitude that Pratt is known for, and now, so is Star-Lord!
