"Watchmen" actor Billy Crudup is reportedly in talks to join Ezra Miller in Warner Bros.' "The Flash."

Citing unnamed sources, Variety contends he'll Barry Allen's father in "Dope" director Rick Famuyiwa's superhero film. "Dope" actress Kiersey Clemons boarded the project in July as Iris West.

Written by Seth Grahame-Smith ("Dark Shadows," "The LEGO Batman Movie") from a treatment by "The LEGO Movie's" Chris Miller and Phil Lord, "The Flash" is expected to begin production later this year.

The DC Films feature was originally intended to mark Grahame-Smith's directorial debut, but he left the project in late April over "creative differences." Famuyiwa was announced to succeed him behind the camera in early June.

Crudup, who played Doctor Manhattan in Zack Snyder's "Watchmen," has a long list of film credits, including "Almost Famous," "Big Fish," "Public Enemies" and "Spotlight." He'll appear next year in Ridley Scott's "Alien: Covenant."

Few, if any, plot details are known about "The Flash." Miller was introduced as the Fastest Man Alive in a cameo earlier this year in "Batman v Superman: Dawn of Justice" ahead of a more extensive role in 2017's "Justice League," which is filming now.

"The Flash" races into theaters March 16, 2018.
