No Alucard.
That character is very difficult to adapt, for him to be treated fairly he should be explored in dept, all his sorrow, internal confilct and stuff, however making a movie/game full of that would be little less than emo. I think Alucard is the kind of character that could be the spotlight in litterature... and only there; a CVgame/movie with the whole "I killed my father but I loved him" thing, neccesary to fully define Alucard by what he is, would be ridiculous in itself, emo as hell and kinda tasteless if badly managed, and let's accept it, Konami's writers are not preccissely Nobel-winners.
Good Luck Cox trying to upt it besides SImon Belmont next time and make it work in 20 hours. 2hours for Alucard in a movie? lol
Well, Alucard could also be a very easy solution for a movie.
Have the movie be about a
female Belmont. She meets up with this odd, powerful dude that is hunted down by human like a monster but doesn't kill them when he defeats them, enlists for his help to hunt down Dracula, he turns her down muttering something like "can't kill dad" (insert slightly more epic quote here), she goes, Drac ultimately defeats her and captures her, boom shaka shaka the second half is about Alucard changing his mind and going down to free CuteChick™ from daddy.
Insert high octane fighting with Matrix moves since he's a vampire-like dude.
Insert ridicolously exaggerated final fight between Alucard and Dracula.
Have him being played by a buff, blonde, good looking dude. Have him fight bare chested. At night. In the rain. Slow-mo.
I can already see the trailers.
Jokes aside, it's definitely not what I'd want from a CV movie, but it would definitely work from a commercial perspective, probably better than any attempt to make a relatable Belmont protagonist when nobody knows who Belmonts are.
It may be a paradox, it may be the Twilight effect, but a "vampire" would be a much, much easier to pull off protagonist.
Edit:
I mean, you pull off a slightly more "attractive" version of this:
Prince Nuada, the ultimate warrior Elfand you can have him pull off the movie with barely any need of dialogue/character development. Once again, I'm speaking from a purely commercial perspective. I share the same fantasy of a wonderfully written saga of drama and introspection over vampirism and duty. Even if it's quite likely that a mindless action movie would be closer to the game's roots than anything else.
