It was announced today that 'Prison Break' star Wentworth Miller had been cast as Leonard Snart aka Captain Cold for CW's 'The Flash.' He will appear in the fourth epsiode and I hope many more to follow. We already know Chad Rook was cast to play Weather Wizard in the pilot...or at least one of the Mardon brothers that can control the weather. 

CW's 'The Flash' stars Grant Gustin as Barry Allen/The Flash, Candice Patton as Iris West, Jesse L. Martin as Iris’s father, Detective West, Danielle Panabaker as Dr. Caitlin Snow, Carlos Valdes as Cisco Ramon, Tom Cavanagh as Dr. Harrison Wells, Rick Cosnett as Eddie Thawne, along with many more surprises to come.

Also announced was a 2 Hour Arrow/The Flash Crossover event that will take place in episode 8 of both shows and that Felicity will be taking a vacation from 'Arrow' to visit Barry Allen on 'The Flash' during episode 4.

“The Flash” will debut October 7th on The CW.
