Teeth Casts
Dental casts were created for the entire cast in the event that someone lost a tooth! The youngsters in the first Harry Potter film, Harry Potter and the Philosopher’s Stone, were all 10-years-old at the time of the filming, which is why they all required dental casts. Radcliffe explained that “because you’ve got a set full of twenty 10-year-olds… they would cast everyone’s mouths,” because there was always a potential that the tiny children would lose one tooth while filming and that tooth would have to be replaced by a fake one.
Dudley’s Weightloss
Between films, the actor who played Dudley Dursley shed a significant amount of weight. Dudley’s transformation from being overweight to being healthy is documented in the novels. As a result of his weight loss in between projects, actor Harry Melling required a special fat suit and facial prosthetics that were developed specifically for him by the makeup team. Despite this, due to his significant weight loss, the majority of his sequences had to be cut from the final cut of the film.
