David Harbour has tackled other-dimensional beings, ice queens, and now, he’ll enter the superhero spy game.

THR is reporting that the star of Netflix’s Stranger Things and the upcoming Hellboy film has signed on to star in Marvel’s Black Widow. The film has Scarlett Johansson reprising her role as the MCU’s resident spy/assassin, and Florence Pugh as the film’s co-lead. Cate Shortland, the filmmaker behind the Nazi drama Lore, is directing the project, which has a script by Jac Schaeffer.

Plot details are being kept under lock and key, but what has been revealed is that it will be an internationally-set story centering on Natasha Romanoff. She is a spy and assassin who grew up being trained by the KGB before breaking from their grasp and becoming an agent of SHIELD and Avenger.

Harbour will lead his first movie with Lionsgate’s reboot ofHellboy, which opens April 12, and recently wrapped his role opposite Chris Hemsworth in action thriller Dhaka. In July, he returns for season three of Netflix’s Stranger Things in which he plays sheriff Jim Hopper.

Black Widow is rumored to hit theatres some time in 2020.
