If you were looking forward to a gestating video game adaptation, it looks like plans for the film have been scrapped. According to Bloody-Disgusting, the film adaptation of the Castlevania is not happening.
Paul W.S. Anderson and Ian Jeffers were writing the adaptation that originally had Sylvain White attached to direct. The site reported that the project had currently been out to other directors and has now apparently slipped into "development hell."
We'll be sure to keep you posted on any new developments if this Castlevania film is resurrected.
