10 Times Actors Broke Character In Movies

10. Johnny Knoxville - The Ringer

Mid-way through the criminally underrated sports comedy The Ringer, Johnny Knoxville finds himself unable to maintain his composure when one of his co-stars drops one of the film's most gut-bustingly memorable one-liners.

Lynn's (Katherine Heigl) partner David (Zen Gesner) spins a lie that he took Steve (Johnny Knoxville) and his Special Olympian pals to the mall for ice cream, at which point Winston (Geoffrey Arend) shouts, "When the f**k did we get ice cream!?"

As Arend fires off the quip, keep your eyes on Knoxville, who promptly cracks up laughing, apparently because the line was improved by Arend on the spot. With that in mind, you can't really blame him.

And yet, the line is so hilarious that director Barry W. Blaustein decided to include it anyway, no matter that Knoxville technically blew the take. Thankfully, seeing him thoroughly lose it only makes it even funnier.
