MTV recently caught up with The Flash screenwriter Marc Guggenheim, who is finishing up the script with Michael Green and Greg Berlanti. He revealed why they ended up using the Barry Allen version of The Flash instead of Wally West or Jay Garrick:
"It's very similar for the whole reason we went with Hal for the Green Lantern. That's the Silver Age character. That's the character people grew up on. That's the name first associated with that character. So part of it is honoring the legacy aspect, and the other aspect is just practical - you can go forward, but you can't really go backward. You can't start with Kyle Rayner, and then do a movie with Hal Jordan.
Just from a practical standpoint, I feel it's better to go in a linear, generational fashion than it is to double back - which is not to say that Kyle and Wally aren't phenomenal versions of the character. They are, and they are near and dear to my heart. We just have to get up to them."
"Flash has a spectacular rogues gallery. You know it's funny, because we've been trying to come up with a good joke about the cast. Let's see... You won't see Chunk in it. We're saving Chunk for the sequel. [Laughs]"
When pressed for further details on the rogues gallery, he refused to say which characters we would see. We'll be sure to keep you posted with any further details on The Flash as soon as we have more information.
