'Arrow' spinoff: 'The Flash' casts Tom Cavanagh as a physicist
According to The Hollywood Reporter, Cavanagh's character of Wells was a "rock star in the world of physics" before his pet project went horribly awry. That would be the S.T.A.R. Labs Particle Accelerator. In the "Three Ghosts" episode of "Arrow," Barry Allen ( Grant Gustin) went home to Central City just in time to get caught in the accelerator's bizarre explosion.
That confluence of events is set to create the superhero known as the Flash.
Unfortunately for Wells, the explosion also means that he's a scientific pariah -- he only gets a shot at redemption when he realizes Barry has gained super speed as a result of the accident.
With the casting of Cavanagh, the "Flash" pilot has almost all of its characters set. In addition to Gustin and Cavanagh, Jesse L. Martin, Danielle Panabaker, Candice Patton, Carlos Valdes and Rick Cosnett are set to appear. One other main role, Hartley Rathaway, has not yet been announced. The character of Barry was introduced in two Season 2 episodes of "Arrow."
Best known as the lead on "Ed," Cavanagh has also appeared on "Royal Pains," "Scrubs," "Eli Stone" and more. If picked up by The CW, "The Flash" will likely premiere in fall 2014.
