Plot details for the film are currently being kept under wraps, but it is based on the Japanese novel Maria Beetle by Isaka Kotaro.
On top of directing, Leitch will supervise the script written by Zak Olkewicz (Fear Street).
The cast for the film, led by Pitt, already includes Aaron Taylor-Johnson (Kick-Ass), Andrew Koji (Warrior), Joey King (The Lie), Brian Tyree Henry (Atlanta), Zazie Beetz (Deadpool 2), Michael Shannon (The Shape of Water) and Masi Oka (Spies in Disguise).
Leitch and McCormick recently signed a first-look deal at Universal and produced the action film Nobody, starring Better Call Saul’s Bob Odenkirk, which is expected to release in February 2021.
