For an untitled drama, the latest Arrow/Flash spin-off is really ramping up its cast.
The potential CW spin-off, which comes from the teams behind Arrow and The Flash and is being described as a great team-up series, already has a number of names attached to it, including Brandon Routh (Ray Palmer/The Atom), Wentworth Miller (Leonard Snart/Captain Cold), Victor Garber (Martin Stein/Firestorm), and Caity Lotz (Sara Lance/Black Canary).
A source has now confirmed to EW that Dominic Purcell will reteam with his Prison Break co-star Wentworth Miller in the upcoming spin-off. As Deadline first reported, Purcell will reprise his Flash role as Mick Rory, a pyromaniac who finds an outlet for his obsession with fire when he teams up with Leonard Snart/Captain Cold (Wentworth Miller) and becomes the villain known as Heat Wave.
The spin-off, which is in development, is not part of the current pilot season.
