Billy Crudup has been a superhero in the past – you can find him glowing blue and possessing enormous power in Watchmen (2009) – and according to Variety, he is preparing to head back into comic book world, this time for the DC Expanded Universe, as he is in talks to play Barry Allen's father in The Flash.
Ezra Miller (The Perks Of Being A Wallflower) is Barry, of course, having been briefly introduced in Batman V Superman: Dawn Of Justice and scoring a more substantial role in next year's Justice League. Assuming the movie keeps to the lore, Crudup will be Henry Allen, who provides support to his son and works as a doctor.
Seth Grahame-Smith (Pride And Prejudice And Zombies) wrote the film, and Rick Famuyiwa (Dope) is in the director's chair, having already cast Kiersey Clemons (Bad Neighbours 2) as Iris West. Ray Fisher's Victor Stone, also known as Cyborg (a fellow Justice League member) is rumoured to be showing up, though their are no real plot details around yet. The film is set for a 16 March 2018 release in the US and we would expect to see it around the same time here.
Crudup was last seen in The Stanford Prison Experiment (which coincidentally also featured Miller) and has several movies on the way including 20th Century Women, Jackie and Ridley Scott's Prometheus (2012) follow-up Alien: Covenant.
