Tomorrow's episode of The Flash , “Flash of Two Worlds,” features the debut of Jay Garrick aka the Flash of Earth-2. Well, technically he debuted in the final moment of the Season 2 premiere, but this is our first full episode featuring the Golden Age character. IGN attended a screening where we got to hear from actor Teddy Sears about taking on the role, and writers Todd and Aaron Helbing about how they brought this comic icon to the small screen.

That was really fun. I wasn't sure what they were going to do, because you look at the 1940 one when he was introduced -- isn't it his old football jersey or something that he puts on? You know, very red and very yellow. I wasn't sure how they were going to handle it. But they have successfully modernized it in this really cool, almost motorcycle jacket sort of aesthetic. The jacket's wonderful. It's all good -- the pants, the boots -- but it's really the helmet. The helmet sort of caps the whole thing off. I love what they did to the helmet too. If you look at the helmet -- and we'll certainly have enough opportunities to -- it's been around. It's beaten up. It's got dings. It's got a wonderful patina to it. It's seen its share of battles. So the detail that the team put into those little things to make it, to have it arrive with a story and a history and a past, that's really what made it work for me. As far as me making it work, they just took my measurements, man, you know? [Laughs] It just fit.It's very exciting, just in that, it's a character that's no longer in the courtroom or wearing a lab coat or something. It's been a nice sort of progression. But yeah, this guy is a uniform, like a handful of other characters I've played. How does it feel? I don't know, just wonderful. It feels like such a tremendous honor to try to attempt to feel this guy out and give him a real third dimension. And that aspect of a third dimension I think is maybe a little bit different than playing the foil in a three-piece suit in a law show or something, someone who can tend to be two-dimensional. I think the goal is to make this guy a 100-percent human being who has a past, who has a history and conflicting feelings and all the things that make humans so wonderful to watch, and so complex. But yeah, that's an interesting point. It is another getup of a different nature, but this one means a whole lot more to me.I think it's going to be sort of a coach/athlete relationship. Jay is the older brother that Barry didn't have. He's more experienced. His attitude is a little bit more confident, and I think he's the teacher to him.In a different way, I think. Last year, he didn't really have anybody that he could speak about being a speedster with. It's not like he go have drinks with Wells and talk about being a speedster, but he can with Jay, and Jay can mentor him on some of the powers that he has and figure out the best way to get him to use those.Yeah, I like the older brother analogy, too, versus father. That is a very different dynamic. There is certainly going to be some overlap, but there are some things you can only talk to an older sibling about that you maybe wouldn't feel comfortable talking to a dad character about. And I really like Grant. As a person, I really like Grant.It's hard not to like Grant.It's hard not to like Grant. But for Jay and Barry, that translates. There's a real desire to be around him and want to lend help, which is also fun to play with.
