Personally, movies based on games are a bad idea. But as a DMC fan, and a film school graduate. If by some miracle granted by every single deity from every religion and mythology known to man I were to get the chance to do it. Here's some ideas I got.
- The overall plot would be in-line with DmC's plot, but with some aspects from the classic series.
- Dante and Vergil's backstory would be the same as the classic series. (Sparda would have rebelled because he "awoke to justice" and died mysteriously, Eva would be human)
- Dante would have white hair from the beginning , and he and Vergil would actually transform into demons when they devil trigger. Besides this, they'd basically have their DmC outfits. (Also, obviously since Eva's human. They're just half-demons, not Nephilim)
- Rebellion, Ebony & Ivory, and Yamato would resemble their classic counterparts (Especially DMC5 in Rebellion's case, loved that damascus steel pattern)
- Mundus (Who's name would be pronounced like it was in the original series) would have a human form, but his demon form would look more like the original version
- Kat and Lady would basically be fused. She'd have Kat's psychic powers and would have some action girl moments, and I would try to squeeze in at-least one scene of her using a rocket launcher. Don't know if I'd name her Kat or Mary, but for the most part she'd be called Lady.
- Arkham would be a secondary antagonist and Mundus' right hand man. He'd have some aspects of Bob Barbas applied to him, and would have been Mundus' 'high priest' who sacrificed his wife in a ritual to become a demon. Yes he would still be Lady's father. Thinking his full name could be Robert Arkham.
- *EDIT*: I may try to work-in baby Nero lol
That's what I got for now
