The Selma moviemaker signed on to helm the film in February (16) but she has now had to drop out due to scheduling conflicts, sources tell The Hollywood Reporter.

The movie, written by Jurassic World director Colin Trevorrow and his collaborator Derek Connolly, follows a United Nations employee, who makes contact with a beautiful woman who may be an alien while monitoring outer space.

Ava and Colin appeared to confirm the reports during an exchange on Twitter in which he told Ava he hoped she would one day make one of his scripts.

She wrote, "Dear @ColinTrevorrow, Can't wait to see one of my favorite scripts come to 'LIFE.' Pun intended. Go get 'em, pal," and he replied, "I’ll keep leaving scripts on your doorstep with high hopes. So many stories, so little time..."

12 Years A Slave actress Lupita Nyong'o still remains attached to the project. She recently scored a Tony Award nomination for her performance in Broadway play Eclipsed.

Ava is next directing TV drama Queen Sugar, followed by TV movie Battle of Versailles and a movie adaptation of A Wrinkle in Time, the children's book classic by Madeleine L'Engle.

Colin is also working on the script for the Jurassic World sequel with Derek. He has handed over the directing duties to The Impossible moviemaker J.A. Bayona so he can concentrate on writing and directing Star Wars: Episode IX, which is set for release in 2019. Lupita also stars in that trilogy as motion capture character Maz Kanata.

Star Wars: Episode VIII is currently in production and is scheduled for release in December 2017.
