Matt Reeves Says ‘The Batman 2’ Villain Has ‘Never Really Been Done in a Film Before’

They could go for one of the really unpopular villains that no one remembers. People like Calendar man or Orca

Some I could think of:

Killer Croc - Probably not a good choice, would need to be working with someone

Clock King - Could be a good villain and fairly open ended character meaning the movie could do what they want with him

Court of Owls - Not sure good as a second movie villain, but could be interesting later on. Would actually be amazing if they built up a series of movies with them pulling all the strings throughout.

Calendarman - Given the more noir style of the last movie, he could be an interesting one, but would probably feel too similar to the Riddler.

I would bet on Hugo Strange.

From the article,

will focus more on the character of Bruce Wayne

and Huge figures out who Batman is, so this will require more focus on who is Bruce Wayne.

Also he's only been done on TV (in Gotham), hence the new to film comment.

Plus he fits the grounded universe that's been established.

Almost all of these have been done before in B:tAS, and done well. Whether or not the primary audience was intended to be children, there was some really solid characterization in that show.

They're already doing Clayface next year.
