Miller's decision to return to the front of the camera after putting on his writer's hat (2013's

franchise) was a conscious one; he cited the often "lonely experience" of spending his days alone as a big factor. Ahead of the episode, the 42-year-old actor answered five questions via email for

and Captain Cold made you want to get back into the swing of TV?

I'd been writing for a few years and it was a lonely experience. Initially I enjoyed sitting at my desk and setting my own hours. Being my own boss. But I started missing the community and the connection you find on set. Especially a TV set. The cast and crew of

Producers Andrew Kreisberg and Geoff Johns intimated that it was your idea to bring Dominic Purcell in for Heatwave. Why did you believe he would be a good fit and what was it like reuniting for the first time on screen since

As soon as they described the character to me I thought of Dom. "Unpredictable, force-of-nature, a little rough-and-tumble...." But I never dreamed it would actually come together. And I'm so glad it did. As men, we couldn't be more different. But he gets me and I get him. And that's true of our characters as well.

Snart's a villain but he's also very human. That's one of the things that drew me to him. The chance to play his various levels. When I watched the pilot I thought, "This is a show where there seems to be a real balance between action and character. They're investing in both." So I knew it wouldn't just be Snart blasting things with his Cold Gun. We get to see the man too.

What similarities might he have to Michael Scofield?

They're both clever, but where Michael is willing to sacrifice himself for others, Snart likes it the other way around.

mythology and it appears Captain Cold is building up his army. What's his drive in stopping The Flash at any cost?

It feels like his motivations are pretty classic. Dominance. Supremacy. First prize in the local pissing contest. It's how men like Snart pass the time and keep themselves amused. Taking what they want when they want. And anyone who gets in the way of that has to be eliminated.
