Jeron Braxton’s feature debut, the animated monster movie Slime has added Winston Duke (Us, Black Panther films) and LaKeith Stanfield (Haunted Mansion, Knives Out).

They join Scott “Kid Cudi” Mescudi (X), Willow Smith (I Am Legend), Teyana Taylor (One Battle After Another), Anna Sawai (Shōgun, Monarch: Legacy of Monsters), John Cho (Murder Bot, Afraid), and John Boyega (The Woman King, Attack the Block).

Brian Ash (The Boondocks) wrote the script and serves as executive producer. The movie will feature an original soundtrack and score by Mescudi.

“Set in a too-near future, Slime follows Muna (Smith), an optimistic but broke young woman who signs up for a paid clinical trial, only to be injected with a mysterious creature’s slime that unleashes destructive powers she can’t control.

On the run, she kidnaps Glenn (Mescudi), the lab worker who injected her, and the two set out on a perilous odyssey through a crumbling dystopian world in search of refuge and a cure.

But as the clock runs out, is Muna transforming into humanity’s worst nightmare or its last, unlikely savior?”

Deadline first Duke and Stanfield joining the cast.
