Director Edgar Wright has found a villain for Marvel’s Ant-Man. He has cast Matt Gerald, who appeared in James Cameron’s Avatar, will play the nemesis for Paul Rudd.

The news was first reported by Deadline, which offered no further details. However, IGN does point out that Gerald did appear in All Hail The King, a Marvel One-Shot that will be featured on the Thor: The Dark World Blu-ray and DVD. There’s no word if he’ll play the same character in Ant-Man.

Gerald has also appeared in Hawaii Five-0, Escape Plan and Dexter. He just finished the Colin Farrell film Solace.

The actor is the latest to join the cast, which includes Rudd, Michael Douglas as Hank Pym and House of Cards actor Corey Stoll. Evangeline Lilly is also reportedly in talks.

Ant-Man opens on July 31, 2015.
