Who would be your ideal Martian Manhunter? The perameters for the casting would be that the actor would embody the character as a martian via complex prosthetics and would also portray his most constantly assumed human form, John Jones. So the actor doesn't have to be a giant or the most well built guy, but he probably should be fairly tall with at least an athletic build. The actor would also have to ne a very strong dramatic and comedic performer. He would be required to portray very subtle emotions and convey a lot through his physical movements and eyes. His voice should also sound mature. Who, under those conditions, would you guys cast as the Martian Manhunter?
