10 Funniest Things That Happened During The Making Of Harry Potter

10. The Three Essays

After directing the first two Harry Potter movies, Chris Columbus was replaced by Alfonso Cuarón, a superb director who brought a much darker tone to the franchise.

During the filmmaking process, Cuarón asked Daniel Radcliffe, Rupert Grint, and Emma Watson to write essays about the characters they play. This may seem like an odd request, but he thought their performances would be even better if they understood their characters as thoroughly as possible.

Daniel wrote a one-page essay and was rather chuffed that he’d managed to do it. However, his sense of pride was quashed almost immediately when Emma arrived with sixteen pages of writing. Rupert, on the other hand, didn’t even do the essay. Whilst this isn’t laugh-out-loud funny, the actors’ responses to Cuarón’s request were an exact reflection of the characters they play.

In fact, Rupert essentially proved he understood his character perfectly, as Ron probably wouldn’t have done the essay, either. And as for Emma's response, her overachiever approach to the essay was remarkably similar to Hermione's attitude to school work.
