The 27-year-old Oscar nominee will play Billie Jean King, the No. 1 women's tennis player in the world in the '70s, opposite Steve Carell's Bobby Riggs in Battle of the Sexes. The movie began shooting on Wednesday and we already have our first look at the two actors in character -- it's quite the trip, too.
The movie, directed by Jonathan Dayton and Valerie Faris (Little Miss Sunshine, Ruby Sparks), also stars Sarah Silverman and Alan Cumming and promises to explore issues of gender equality and sexuality. It's the match that became the most-watched televised sporting event of all time, and if this first look is any indication, we will most definitely be watching the movie version too.
