Lawrence, Schumer have `official first draft` of their film

Los Angeles: Actress Jennifer Lawrence and comedy star Amy Schumer have finished writing the script of their highly anticipated movie.

The 25-year-old "Hunger Games" star said that they will go ahead with the project "soon," reported People magazine.

"We have finished writing it. We have an official first draft. I am going to try and fit it somewhere into my ghoulish schedule," Lawrence said.

She also gushed about how much fun she had while working with Schumer, 34.

"It was hilarious, because when you're writing a comedy it's not good enough unless you're laughing out loud. So I'm laughing at my pages and I'm laughing at her pages and thinking that the whole process is hilarious. I'm thinking we've got a pretty funny, good movie," she added.

The two first announced their collaboration last summer. The real life friends will play sisters in the film.
