Oscar-winning star Meryl Streep puts her acting success down to not caring about her looks. The DEVIL WEARS PRADA star insists not worrying what you look like is a vital tool when acting, but fears too many female actresses nowadays care too much about what they look like. She says, "I think the most liberating thing I did early on was to free myself from any concern with my looks. "For an actress, worrying about appearance is a horrible, horrible trap. I didn't have confidence in my beauty when I was young. I felt like a character actress and I still do."
