From what i heard Wentworth gave the Creators of The Flash the idea of casting Dominic Purcell as Heatwave do to the great acting the 2 had on Prison Break and that it would add to the Friendship that Snart and Mick had for the Series
Prison Break, I believe it was from s1. ^_^ Wentworth(Leonard Snart) and Dominic(Mick Rory) were in it together, main characters. They were brothers, though. xD
