Jennifer Lawrence finally gave some plot details about that script she is writing with comedian Amy Schumer. The two have been talking about it for awhile and it’s still not completely clear when it is going to get made.

News that the two are writing together first surfaced in August and it’s been reported that the two are going to play sisters. Schumer did tell Access Hollywood over the weekend that the script is “funny,” “dirty” and “real.”

Lawrence gave some more details in an interview with Entertainment Tonight Wednesday in Berlin, where she’s promoting The Hunger Games: Mockingjay - Part 2. She surprisingly revealed that Schumer will play the straight man in the movie, while she is wild sister.

“Amy, in this movie, she has it very together. It's her lifelong dream to be a flight attendant. She works at the airport,” Lawrence told ET. “And I’m a mess.”

The Oscar winner added that she realized that she and Schumer are “made for each other” after seeing Trainwreck. She said that, after reaching out to the Inside Amy Schumer star, things just fell together.

“We both have very similar senses of humor, obviously and aren't afraid, which is a good and bad thing, because I don't know what our movie will be rated. And we're both very blunt,” Lawrence said. “So we've gotten through a really strenuous process without ever fighting, because we're both very straightforward.”

It’s unknown what studio will be making Schumer and Lawrence’s film, but you can bet someone is working the phones in Hollywood to get it. Both stars are busy, so who knows when we'll even see this movie.

Lawrence is just starting her Mockingjay 2 publicity tour and will then have to promote David O. Russell’s Joy, which opens on Christmas Day. She’s also finishing work on X-Men: Apocalypse and Passengers.

As for Schumer, she’s got a book to write and will be starring in Fox’s Mother/Daughter.
