Seven years after appearing as Dr. Manhattan in Zack Snyder’s Watchmen, actor Billy Crudup is returning to the superhero genre with the Flash movie, set within the Snyder-spawned DC universe.

A source confirms to EW that Crudup will feature as Barry Allen’s dad, Henry, opposite Ezra Miller as the titular scarlet speedster. It’s a character currently played by John Wesley Shipp on the small screen in The CW’s The Flash, starring Grant Gustin.

Crudup recently appeared in the Oscar-winning Spotlight and The Standford Prison Experiment, while he has upcoming roles in Alien: Covenant, the Netflix series Gypsy, Jackie, and 20th Century Women.

Miller first appeared as Barry Allen in Batman v Superman: Dawn of Justice before popping in for a Suicide Squad cameo. The Flash will next fight alongside Batman (Ben Affleck), Wonder Woman (Gal Gadot), Cyborg (Ray Fisher), and Aquaman (Jason Momoa) in next year’s Justice League before getting his own film.

Set for release on March 16, 2018, The Flash will be directed by Rick Famuyiwa (Dope) based on a screenplay by Seth Grahame-Smith, who worked off a treatment by Phil Lord and Chris Miller. Kiersey Clemons will portray Barry’s love interest Iris West, while Fisher will reprise Cyborg.

Variety was the first to report Crudup’s casting.
