POTTER: Why Emma wore wig in final film Deathly Hallows

Emma Watson has revealed that she had to wear a wig to film some of the scenes in the latest Potter movie.

She plays Hermione Granger in the Potter series, who is famous for her long curly hair.

But when the cast had to re-shoot some of the final scenes at the end of 2010 Emma had already cut off her long hair.

She said: "I did have to wear a wig, but you'd never know. I will be amazed if anyone can tell where that scene slots in."

Emma said she was really excited about the last film in the Potter series.

She said: "It looks incredible - I'm always biased but the ending looks epic. I'm very excited."

The final Harry Potter film, Harry potter and the Deathly Hallows Part 2 is released in July.
