Amy Schumer and Jennifer Lawrence are writing a movie together that will star both of them as sisters. That bit of news titillates fans of both actresses, many of whom could hardly contain themselves last month when pictures of the two on vacation together hit headlines.

Amy Schumer and Jennifer Lawrence are burning through the writing of the script, which Jennifer Lawrence broke news of to the New York Times this week.

“We play sisters,” Jennifer Lawrence said. “We’re almost done writing. It just flowed out of us. We’ve got about 100 pages right now.”

“Amy and I were creatively made for each other. We have different flavors. It’s been the most fun experience of my life. We start the day off on the phone, laughing. And then we send each other pages. And we crack up. I’m flying out tomorrow to see her in Chicago. We’ll write a little bit with her sister, Kim, who worked with Amy when she was writing ‘Trainwreck.’”

“I emailed her after I saw ‘Trainwreck’ and said, ‘I don’t know where to get started. I guess I should just say it: I’m in love with you,'” Lawrence said. “We started emailing, and then emailing turned to texting.”

The sparkly-yet-grungy friendship between the two super-women of Hollywood blossomed into headline-grabbing Instagram posts that Schumer had to explain to Jon Stewart.

Amy Schumer told Jon Stewart how Jennifer Lawrence, the highest-paid actress in Hollywood today, ended up on a boat with her and her friends.

“I was like, ‘Oh, we’re going on a boat tomorrow. You should come.’ It was kind of a hypothetical,” Schumer said. “And she was like, ‘I think I’m coming.’ And I was like, ‘Oh my God!'”

“She’s the coolest chick you’ll ever meet,” Schumer said. “She’s the best hang, she was like one of the gang.”

That’s when Jon Stewart threw out the idea that Schumer and Lawrence do a film together. He said of one of the pics Shumer had posted with Lawrence:

“That’s your next movie poster. Tell me that’s not a cop movie.”

And now they’re doing a movie together. Jon Stewart is still giving gifts to the world.
