He's also the lead in The Gentleman (the more relatively stoic, younger brother to his elder brother being an absolute freaking mess that got into trouble *badly*).
And now we have Isaac as Apocalypse, the two forgemasters of Dracula are now X-Men villains, the creators definitely watched Castlevania, that Wolverine and Nightcrawler fight scene was so castlevania, especially Nightcrawler's elegant fighting style reminded me of Alucard, which is a good thing bc that would mean Castlevania is having an impact on western animation.
