VIENNA (February 8, 2013)--Oscar-winner Mira Sorvino says she could see giving up acting for her other passion, human rights advocacy.

While saying she loves acting, she describes her efforts to stop human trafficking as "my calling" and that, she says, is so important that "in a decade or so, I wouldn't mind just switching to a career in humanitarian causes."

Sorvino spoke to The Associated Press on Friday after her term was extended as the U.N. Goodwill Ambassador to Combat Human Trafficking.

Sorvino, 45, won an Oscar for her role as a prostitute with a golden heart in Woody Allen's "Mighty Aphrodite."

She's had meaningful roles in more than 50 films and TV productions over the course of a two-decade career, and has also received a Golden Globe and a host of nominations reserved for the world's best actors and actresses.
