Peter Jackson's movie spectacularly manages to fail the Bechdel Test on every single count.
However, in Jackson's defense, he was working from a classic novel. In Tolkien's The Hobbit, there are no female characters at all. Hence the fact that Galadriel turns up is actually an insertion by the director.
Nor is it likely to be his last. In March 2011, the Mary Sue reported that the latest trilogy is likely to include at least two more female characters. While Primula Brandybuck does get a mention in Tolkien's wider work, she's not actually in this novel. Nevertheless Fran Walsh will play her in one of the future movies.
The final female will be a wood elf played by Saorse Ronan.
Tolkien purists are not going to like these insertions at all. But they wouldn't. The question for those trying to evaluate the silver screen portrayal of female roles is will they actually count?
Galadriel is shown in The Hobbit: An Unexpected Journey as the final word in just about everything. It's even implied that Gandalf and the dwarves have to seek her permission to go on their quest. That's for no good reason that I could ascertain.
She's also telepathically wise in uncovering all potential deceit in her presence. Though not the one that actually matters. (The entire franchise would collapse, if Galadriel was consistent. She'd know about Sauron as soon as he entered Rivendell.)
Galadriel is strong, graceful, beautiful, womanhood in perfection. She's Galadriel! And in her wisdom, she will only trust men in her councils or on her quests. What kind of role model is that precisely?
And that part where she was messing with Gandalf's hair, was that flirting with him or mothering him? I really can't recall any of that in Tolkien's books. But as Galadriel wasn't even there in this particular book, then I suppose that the floor was wide open with what to do with her.
