Ron Perlman

Ron Perlman was awesome as Hellboy. And his voice was even more awesome in the Teen Titans series, where he actually became Deathstroke. So he would be an obvious choice, especially since he does look like a grizzled Slade Wilson, who can be very nasty and who has no time for playing games.

Of course, he is a bit old. Actually, he may be too old – but this is the only drawback. With the movie magic nowadays, he could hold his own against the entire Justice League if needed. So this needs to happen. Among the many actors listed until now, I would be the happiest if Ron Perlman got this role.

Plus, a Deathstroke role would make up for the lack of Hellboy 3. We all know how much Perlman fought for this movie to be made, only to be refused because the franchise didn’t made Marvel-level money. Shame, shame, shame.
