Wrong choice for Rachel?

Wasn't a big issue for me, but yes she is perhaps the least beautiful looking female actor in the franchise and I would include Gordon's wife and the female cop in that. Not ugly or anything but more on the plain side.

In my opinion, Katie Holmes was. Christopher Nolan cast her as the childhood friend of Bruce Wayne in Batman Begins because she perfectly fits the role, which was created specifically for this trilogy. Unlike most of the other females that populate the Batman mythos, Rachel is not a femme fatale-like figure. She is the daughter of a maid, and the death of Thomas and Martha Wayne sent her on her hero journey - to become a lawyer, and eventually a prosecutor, to fight back against the corruption and lawlessness that had crippled Gotham City and ultimately led to the murder of the Waynes. Bruce goes the route of the vigilante, but Rachel works at the problem from the inside, attempting to fix a corrupt system by standing up to those in power within it, including her boss (DA Finch), Dr. Crane, the police, and gangsters like Carmine Falcone. Ms. Holmes plays Rachel exactly right: she’s a naive idealist, a goody-goody who is obviously over her head, but charges into the storm with no fear, powered by her impeccable morality (or self-righteousness, if you prefer). Look at her scenes when she confronts Bruce and slaps him out of his state of self-pity, or when she faces Crane and doesn’t even flinch at his creepy veiled threats.

I heard years ago that Katie Holmes turned down the Dark Knight for Mad Money, lmao... She always will be the perfect Rachel.

I read that her brother Jake was considered for the role of Batman in this series. Maybe the producers had inroads with the Gyllenhaals, so Maggie was chosen for that reason
