I love how she's not wearing skimpy clothing. I DESPISED the Arkham Asylum version of Harley Quinn. 
 
Regardless, the movie would be much better off without out her at all.

Nolan won't be able to top the 2nd movie.  I don't care how many villains will be in the 3rd movie.  No other villain can top The Joker and no other actor could top Heath Ledger.

I feel like at the very least Harley Quinn needs to be a manic minx.  She's no good look so mopey.

The blood splatter is too much. In fact blood might have been the one thing that would have turned the Dark Knight from PG-13 to R.  
 
And yeah this is an old Photoshop, back when fans titled Batman 3 as Batman: Gotham City.

Yeah I'm 99% sure the lady villain is going to be Catwoman. Harley Quinn is too tied to the Joker and they're definitely not having him in the movie, and all of Batman's other female villains are juuuust this side of too ridiculous or too superpowered. Catwoman can work as a thief, there's no need for the ridiculous supernatural element that even the comic isn't sure it wants around. 
And I've actually heard that Tom Hardy will be playing Hugo Strange, which would make sense with the new game.

My gut reaction was "ewwww."

Can't wait till this movie 
Also Im going to try and be an extra hopefully 
Its being filmed mostly in New Orleans

They need to stay away from Harley Quinn, I think.
