If we're still wishing for a Castlevania movie (now that Paul Anderson and his stupid Sonia "Gotta-Fit-Milla-Jovivich-In-Somehow" idea have been canned), I would prefer to see Guillermo Del Toro directing and Garrett Hedlund as Simon Belmont.
I'm not opposed to Sonia at all (she & Iga's complete denial of her existence was my sig for a while after all), but Anderson makes my skin crawl...in a bad way.
Robert Carlyle would be just a bit old for Gabriel & that makes me sad because he's perfect in every other way. He'd be a fine Dracula though I must say.
Dwaine looks like he could be a pretty nifty Gabriel, but I wouldn't say he's perfect...just something...I dunno, not quite there for me. He's probably a better pick than most others & there isn't really a 'perfrct' match, so maybe I'm just expecting too much. Maybe it's just that I've seen so many terrible video game to big screen transitions I just don't wanna see a series this beloved marred.
