Kellan Lutz as He-Man: has vocally pitched himself for the role. And he has the potential to have his breakout movie yet.
Nathan Jones as Beastman: I like! (Although I would like Tyler Mane l.jpg to get in here as well)
Robert Maillet (WWE Kurrgan) as Clawful (if he was in the script) kurrgan.jpg
John Glover as SKELETOR: IMO HANDS DOWN! john-glover-photos.jpg
Lucy Lawless as the Sorceress: I'm interested
Tricia Helfer as Evil Lyn: WHOAH
Just a few that came off the top of my head.
