Jennifer Lawrence Is the 'Mess,' not Amy Schumer in Their New Movie

Jennifer Lawrence will be the trainwreck in the movie she's writing with Amy Schumer.

The Oscar winner is currently in Berlin promoting the final Hunger Games film, Mockingjay - Part 2, but when we sat down with her, we had to ask the actress about one of her other projects: The comedy where she and the Inside Amy Schumer Emmy winner play sisters.

Schumer recently said the script is "funny," "dirty," and "real," and Lawrence confirms to ET, "Yep! It's is all of those things."

So what's it actually about? And who will play the wilder 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 reveals. "And I'm a MESS."

If it's anything like what we're imagining in our head -- Trainwreck meets Tina Fey and Amy Poehler's Sisters meets any interview Lawrence has ever done, with a sprinkle of Schumer's stand up mixed in -- it's already our favorite movie ever. Or maybe it's a remake of View from the Top.

Of their highly publicized friendship-turned-writing partnership, Lawrence says it feels "very cosmic." "I watched Trainwreck and I was like, 'Yep, we're made for each other,'" she recalls.

"I reached out and everything just happened so quickly," Lawrence explains. "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. So we've gotten through a really strenuous process without ever fighting, because we're both very straightforward."

Meanwhile, Schumer has said that her friendship with Lawrence makes her feel like Danny DeVito in the movie, Twins. (She was only joking though.)

But even though Lawrence is penning the script this time, don't expect her to write in any cameos for her Hunger Games costars, Josh Hutcherson and Liam Hemsworth. Actually, don't expect any boys at all.

Lawrence tells us, "No, no, no, no, no...There's not really boys in it."

Plus, Schumer reveals to ET that her upcoming memoir will get "heavy":
