THE FLASH: Andrew Kreisberg Praises Wentworth Miller's 'Captain Cold' And More

The hardest thing is that some of these characters have been around since the '50s and '60s, and they could very easily head into camp. And when you hire people like Wentworth Miller [as Captain Cold] and Dominic Purcell [as Heat Wave] and Rob Knepper [as Clock King], some of these outlandish comic book characters become very grounded and very scary and very real. I mean, with Wentworth, no pun intended, he's just so cool -- he's so cool, like Clint Eastwood. He's like an Old West gunslinger, and that's sort of how we portray him. You're only as good as your villain, and especially in movies, some of the Batman movies have had some of the greatest actors: Heath Ledger and Liam Neeson and Tom Hardy playing these villains and they really feel like threats. And sometimes on TV it's harder to make that happen, and we've been so blessed on "Arrow" with John Barrowman and Manu Bennett, and on "Flash" on Episode Four we've got Wentworth Miller, and in Episode Five we have Clancy Brown [as General Wade Eiling]. So we just feel so blessed that we've been able to attract the kind of talent we have, because in addition to the visual effects, if you don't have these amazing actors it's just a cartoon.
