Harry Potter star Emma Watson says she wants to star in a musical stage show soon.pThe 22-year-old actress, who had to perform routines from famed musical `The Rocky Horror Show` for her new film “The Perks of Being a Wallflower”, said the work gave her a taste for singing and dancing, reported Daily Star. “I love musical theatre, so, I would love to do a musical soon, that would be wonderful… “I was terrified of the Rocky Horror scenes, but, as it turned out, it was fun, and once I got over how weird it was to go from wearing knitted jumpers to corsets and fishnets, I got it together… (It has given me) a taste for cabaret and singing and dancing,” she said.
