Hollywood has been abuzz since the announcement earlier this year that Jennifer Lawrence and Amy Schumer (Trainwreck) were working on a film script together. Now Lawrence has shared some details on the yet-untitled project.  Lawrence is currently doing a press junket for the highly anticipated finale of The Hunger Games series, Mockingjay – Part 2.  In an interview with Entertainment Tonight, the Oscar winner shed some light on the nature of the film, which grew out of the actresses’ friendship:

I reached out and everything just happened so quickly. 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.

The two will play sisters in the film, which Schumer has characterized as “funny,” “dirty” and “real”. According to Lawrence:

Amy, in this movie, she has it very together. It’s her lifelong dream to be a flight attendant. She works at the airport. And I’m a MESS.

Schumer’s sister and writing partner Kim Caramele is assisting on the script.

Lawrence can next be seen alongside her Silver Linings Playbook and American Hustle co-star Bradley Cooper in Joy, reuniting the duo with director David O. Russell. The film is slated for a Christmas Day release.
