Plot details are being kept muzzled, but the pic is described as being in the assassin genre with a story that spans multiple generations. The entire cast is envisioned as being all-female, with Gillan the cornerstone.

Kill Bill, the opus by Big Bad Wolves fan Quentin Tarantino, and Edgar Wright’s Baby Driver are the touchstones of the project, with "stylish," "snappy" and "violent" its watchwords.

The Picture Company partners Andrew Rona and Alex Heineman will produce Gunpowder Milkshake through their overall deal with Studiocanal.

Gillan, who last year made her directorial feature debut with the indie The Party's Just Beginning, has risen to be a key player in the Marvel Cinematic Universe, appearing as Nebula in the two Guardians of the Galaxy movies and last year’s $2 billion hit, Avengers: Infinity War. She is slated to return for Avengers: Endgame this summer.

The actress is also one of the stars of the rebooted Jumanji franchise and will shoot Jumanji 2 alongside Dwayne Johnson, Kevin Hart and Jack Black in February. The plan is to lens Gunpowder Milkshake after that, with production eyeing a Berlin shoot in the spring.

Gillan is repped by UTA, Troika and Jackoway Tyerman.
