7. Jonah Hill in ‘22 Jump Street’
In 22 Jump Street, Jonah Hill’s high-pitched scream during a scene with a cockatoo wasn’t acted. Hill is genuinely scared of birds, which resulted in an unplanned yet hilarious scene.

The actors had no idea what was going to happen, so when the monster appeared from John Hurt’s chest, they were really frightened about their co-star. This resulted in true astonishment and shock… exactly what Scott was attempting to achieve!
