I don't understand why people are interested in seeing Talia Al Ghul.
What would be interesting, besides a plot point to tie into the first film, about Ras' daughter coming to Gotham with League of Shadows in hand to get revenge on Bruce for offing her father?
We would just get a scene like this:
Talia: You killed my father!
Batman: Who?
Talia: My name is Talia...Al Ghul!!!!
Batman: Oh.
Talia: Now you shall pay with your life!
Batman: Great.
They fight. Batman wins. The End.
Plus, from what I've seen of the character, her love for her father and her love for Bruce are a crucial internal conflict for her, but with Ras dead and Liam Neeson certainly not going to return for Batman 3, this version of Talia would have no father to fed for or make a defining choice with...she would only be fighting to honor his memory and not actually have him physically there manipulating her feelings and emotions for Bruce.
I don't think Talia would be interesting at all really.
If you want a new female... go with Catwoman...
1. fans/non-fans know her
2. she's gimmicky, like Joker, Two-Face, etc. Talia is just... a woman. There's nothing that "sells" about her. A hot chick in a cat costume??? awesome! a killer clown??? awesome!!! a guy with half his face burnt off??? awesome!!! a woman who loves her father??? eh? what? um ok.
3. Other themes can be explored.. duality, Bruce falling in love with a fellow "freak", etc. Batman being faced with falling in love with a criminal, fellow vigilante, etc. With Talia all you get is another "revenge" plot.
4. SHE'S FREAKING CATWOMAN!!!!
Okay, so I said my piece.
Catwoman is waaaaaaay cooler than Talia and I would be MUCH MUCH more excited to see Nolan's vision of her than Talia Al Ghul.
So why is Talia so interesting? Anyone want to defend her and the choice to have her in Batman 3, because I don't get it.
