I'm like Billie Jean King's creepy friend now, says Emma Stone

Oscar-winning actress Emma Stone has revealed that she became a real 'creep' while filming Battle of the Sexes.

The actor shared that she had to observe Billie Jean King really closely while they were taking to prepare for her role, reports Contactmusic.

She said, "It was such a thing to figure out how her hands moved and the way she moves within her body. I was a real creep. So now if we do an interview or we're sitting and talking, I find myself staring at her and watching how she's moving all the time, which I don't need to do any more. But that's how I relate to her. I'm like her creepy friend now!"

The actress also shared that she steeped herself in vintage TV footage to get into the skin of the role. "We quickly learned that the choreography would be the most important thing because learning how to do a serve or backhand like Billie Jean was more of an impossible dream than a reality! I really thought through the physicality."
