Actor Sean Kleier (Happyish, Odd Mom Out) has joined the cast of Ant-Man and the Wasp in what is described as a pivotal but currently unnamed role, That Hashtag Show reports. Kleier’s character is said to be a Special Agent and (possible spoilers) is described as “the ‘mole’ of the story.”

That Hashtag Show speculates Kleier could be portraying a villain along the lines of Geoffrey Ballard, a character who in the comics was a CIA Special Agent turned super villain, having donned the costumed identity of Centurion. Ballard had ties to Tony Stark’s Iron Man, Bill Foster, and S.H.I.E.L.D.

The site was the first to reveal Marvel Comics character Bill Foster would make his Marvel Cinematic Universe with Ant-Man and the Wasp. (Marvel Studios would later reveal during San Diego Comic Con that The Matrix and Batman v Superman: Dawn of Justice actor Laurence Fishburne will portray scientist Bill Foster, who in the comics worked as the super-sized hero Goliath.)

The Ant-Man sequel kicked off production earlier this month, again under director Peyton Reed. Paul Rudd and Evangeline Lilly will reprise their roles as Scott Lang/Ant-Man and Hope Pym / Wasp, respectively, with Kleier boarding a cast that includes Michael Douglas as Hank Pym, Michael Pena as Luis, T.I. as Dave, David Dastmalchian as Kurt, Judy Greer as Maggie Lang, Abby Ryder Fortson as Cassie Lang, Walton Goggins as Sonny Burch, Randall Park as Jimmy Woo, Hannah John-Kamen as the villainous Ghost, Laurence Fishburne as Bill Foster, and Michelle Pfeifer as Janet van Dyne, a.k.a. the original Wasp.

From the Marvel Cinematic Universe comes a new chapter featuring heroes with the astonishing ability to shrink: Ant-Man and The Wasp. In the aftermath of Captain America: Civil War, Scott Lang (Rudd) grapples with the consequences of his choices as both a Super Hero and a father. As he struggles to balance his home life with his responsibilities as Ant-Man, he’s confronted by Hope van Dyne (Lilly) and Dr. Hank Pym (Douglas) with an urgent new mission. Scott must once again put on the suit and learn to fight alongside The Wasp as the team works together to uncover secrets from their past.

Ant-Man and The Wasp hits theaters on July 6, 2018.
