Amy Schumer and Jennifer Lawrence no longer planning sister comedy

Amy Schumer and Jennifer Lawrence's long-awaited sister comedy is unlikely to ever come to fruition.

The two actresses had revealed in 2015 they were writing a screenplay for a movie in which they'd play sisters but now the 'Trainwreck' star thinks too much time has passed for the project to work.

Speaking to Variety for their Power of Women issue, she said: “I don’t think it will ever happen. It was just, like, life kept going. My family was going through a rough time. I don’t want to say any more than that.”

Jennifer, 33, agreed: “Now that we’re older, a sister comedy might not resonate as much."

But the pair still want to do something together.

Amy, 42, said: “The way we’re hoping our careers go, we might do something with more grit and teeth.”

Her friend added: "We have every intention of working together.”

Coming up for Amy is the Adam Sandler-produced 'Kinda Pregnant', and she has high expectations for the movie, which has wrapped filming but doesn't yet have a confirmed release date.

The actress - who wrote the script - said: "I'm striving for it to be one of the 10 funniest movies of my lifetime.

"I think it’s going to be as funny as Trainwreck."

Amy's last two movies, 2017's 'Snatched' and 2018's 'I Feel Pretty' were both poorly received, and part of the few projects which she didn't write herself.

Not naming the films outright, she said: “I’ve done projects that weren’t the vision I had for something."

The comic - who has four-year-old son Gene with husband Chris Fischer - is also kept busy with her TV show 'Life + Beth', which she writes, directs and produces, as well as stars in, and she thinks it has taught her a lot.

She said: “This is a very different project for me, because I wear so many hats.

“I’m learning more and getting better at it, and it makes me feel like I’m on the right path.”
