Tom Cavanagh, the former star of NBC's Ed, has joined the cast of the CW's The Flash pilot as Harrison Wells, "a rock star in the world of physics and the mind and money behind Central City’s S.T.A.R. Labs Particle Accelerator."
"He becomes a pariah after the lab’s explosion, but he charts his path to redemption when he discovers that his failed experiment had the unintended consequence of creating the world’s fastest man," reads The Hollywood Reporter's description of the role.
The pilot is reportedly near the end of its casting process with just Hartley Rathaway (Pied Piper in the comic books) remaining to be cast.
So far joining start Grant Gustin as The Flash/Barry Allen are Jesse L. Martin as Detective West; Candice Patton as West's daughter and Barry's love interest Iris West; Danielle Panabaker as bioengineering expert Caitlin Snow (Killer Front in the New 52); Rick Cosnett as Detective Eddie Thawne (likely the show's equivalent or relation to Professor Zoom/the Reverse Flash); and Carlos Valdes as Cisco Ramon, a "mechanical engineering genius and the youngest member of the team of scientists at STAR Labs" (and Vibe in comic books).
Arrow's Greg Berlanti, Andrew Kreisberg and director David Nutter will serve as executive producers. Berlanti, Kreisberg, and Geoff Johns will write the pilot script, with Nutter directing. Melissa Kellner Berman will serve as co-executive producer.
