Lobo
I've been spamming the Lobo boards with Manganiello posts, now I'm gonna spam here with Lobo posts.;p
Long story short: Joe is the only person who can play Lobo that I can think of. He's got the potential for pure savagery. His body, his wolfish face all look like he was born for that role. Plus- he's got experience as a stuntman which would be perfect for action scenes. He could play a main role in a blockbuster, which I guess would be good for him.
Someone get in touch with his agent and get him on board. Lobo deserves this!
