Jennifer Lawrence and Amy Schumer Are Collaborating on a Screenplay

"We play sisters," Lawrence said. "We're almost done writing."

Lawrence, 25, explained that she first reached out via email to Schumer, 34, after seeing her film, "Trainwreck" a few months ago. ("[I] said, 'I don’t know where to get started. I guess I should just say it: I’m in love with you,'" she recalled.) They began a correspondence, and then found themselves texting each other. Soon after, Schumer invited Lawrence to go on vacation with her and her friends.

"We really hit it off, to say the least,” she said. "[Writing this film has] been the most fun experience of my life."
