either way it should be an unknown to the public. hence it's got to be either gunter or o'hearn! they both look the part, both have some acting experience and screw the american public if the producers think either gunter or mike is too big for the role. gimme a break! it's He-Man get the name for christsake! besides whose the audience for this movie anyway. that's who the producers should be thinking off during casting! he-man isn't supposed to appeal to a broad audience like spiderman,superman or batman. and i doubt if the budget is going to be blockbluster money big anyway.
the audience for a he-man movie would be guys interested in seeing a huge kick butt actor (gunter or o'hearn) and for women into huge muscle, the little boys who like comic books with their gigantic superheroes drawn that way and yes, i guess it has to be said gay men.
