Catwoman had her chance.

Red hood because he is just bad ass

Ra's al Ghul, because I think a film with him as a central character has a lot of potential. They could for instance do a film highlighting his background and origin as a man who has lived for centuries and has seen the world change thanks to the regenerative qualities of the Lazarus Pits. A background similar to that as revealed in the Batman: Birth of the Demon TPB.

A modern Mr. Freeze movie could be interesting...

Ra's al Ghul.

I would watch a Harley and Ivy film. :)

A Bane movie could be awesome too.

A scarecrow movie would be good

Red Hood is the obvious choice since he's more anti-hero than villain, but I went with Harley Quinn because I think she could carry a film with a few key supporting characters, either a Gotham Sirens setup or the Suicide Squad setup. Come to think of it, Amanda Waller probably counts as a Batman villain still, give her a film.

i would say a joker film based on him and his background most people underestimate his background. If you take the time and read the comics, his wiki and books you will find he has an amazing story line i think he is awesome.

Joker. Rated R

A movie could be made about anyone but which one would work that is a bigger question.

I only expect Red Hood,Catwoman and Bane movies to do well.Joker can sell himself for a solid opening weekend if nothing else.

Make a Catwoman heist flick. Just make it good.

It could be about how he makes his way into the Crime Syndicate ... including how he blackmails the other members ....

Guess I'm the only one to vote for Hugo Strange haha. Hugo Strange is such a mysterious character to begin with for me. I think he's the type that would definitely have enough story line to get divulged in. I do agree a Poison Ivy and Harley Quinn movie sounds amazing though! Mad Hatter was tempting too, but good old Jervis doesn't seem like he has enough back story to make an entire movie out of, no matter how much I love the villain.

A lot of Batman villains deserve a movie but the real question is which one of these would work in a movie.

Something similar to Selina's Big Score?

@citizenbane: agreed.

Catwoman deserves justice. Think of where that character would be now if they made a good Catwoman movie instead of the one they did make.

There is a lot of interest in this character, and a lot of story telling potential. I like the heist idea.

Welp, we got Joker. I vote Bane now

I'd like to see a Red Hood movie.

Joe Chill and Harvey Dent origin into Two-Face!
