5) Ron Perlman
We may have already suggested Ron Perlman as a possible J. Jonah Jameson in Spider-Man: Homecoming, but in retrospect he would be a much better fit for Slade Wilson. As he proved in Guillermo del Toro’s Hellboy movies, Perlman has the swagger and acting chops to pull off a great performance despite being hidden behind a mask.
Perlman is also the only one on this list to have previously played the character. A veteran of DC animated works (he’s also been Bane, Killer Croc and Sinestro), the actor voiced Deathstroke in both the Teen Titans TV show and the Justice League: The Flashpoint Paradox movie.
This doesn’t really mean he is any more likely to land this role, however – Mark Hamill’s been voicing the Joker for years but no one has offered him the part in live-action. Still, Perlman has the look and the voice to be a terrific on-screen Deathstroke.
