Time out. Zack Morris? Yes. Zack Morris. Gosselaar really has the whole Flash package; the look, the persona, and the range for the humanity of Barry Allen with the heroics of the Flash. Not only that, Gosselaar has the pitch-perfect voice for someone like Barry Allen, and would do well in forms of contrast to the other heroes in a Justice League movie. Check him out in his currently running and vastly entertaining Franklin & Bash. Could you see him as a forensic, humble, likable superhero? I most certainly could. Gosselaar is my number two pick, right under Matthew Morrison. What do you think? Who are some actors you'd like to see take up the challenge of being the fastest man alive?
