#8 – Green Eyes and Buck Teeth
The producers of the first movie about Harry Potter tried to make Daniel Radcliffe green-eyed by making him wear contact lenses. Producers wanted Radcliffe to wear contacts so that his character could be true to the book, in which Harry has green eyes. However, Dan had a bad reaction to the contacts so the decision of him wearing contact lenses was called off.
Also, Emma Watson aka Hermione was supposed to wear buck teeth. However, Watson’s speech was quite funny while she was wearing fake teeth so the producers decided to have her not wear them.
