Leslie Mann and Janelle Monae will join Steve Carell in an upcoming drama from director Robert Zemeckis

The untitled feature is based on Jeff Malmberg's 2010 doc Marwencol, which followed a man who builds a miniature WWII-era village as a way to recover from a violent assault. Zemeckis co-wrote the screenplay with Caroline Thompson.

The director will produce via his Uni-based ImageMovers, along with Jack Rapke and Steve Starkey, as well as Cherylanne Martin. Malmberg and Jackie Levine will exec produce. Maradith Frenkel and Yellin will oversee the project on behalf of the studio.

This marks the first role for Monae since her big screen debuts in awards contenders Hidden Figures and Moonlight. The Grammy winner is repped by WME.

Mann was last seen opposite Robert De Niro in the dramedy The Comedian and will next be seen in the Kay Cannon comedy The Pact. She is repped by CAA and Hansen Jacobson.
