Magpie is mostly memorable for looking like a reject from a Mad Max movie and for recently being killed in the comics. But she was also at one time a feared villain, who had an obsession with jewels that were named after birds. You'd think that would be a very limited specialty, but for some reason, Gotham City had a lot of these (the eagle's heart, the robin's egg, the falcon's eye). She made squawking noises and lame bird puns and all the stuff you'd expect from a fourth-rate Batman villain. By far the most amusing part of her first appearance in Batman comics was how Robin let her get away by being too gentlemanly (click for a larger version):
Pros: There was a time when movie villains sorta looked like that, with weird hair and weird costumes. Like Daryl Hannah in Blade Runner. It might be cool to bring that back.
Cons: It would not be cool to bring that back in a Batman movie though. Also, if anyone's going to be stealing jewels named after birds, it ought to be the Penguin
How I'd do it: To make her work, she'd have to change so much that she'd basically be the lady Penguin, or Catwoman but with birds.
Casting Guesses:Chyler Leigh, who I just learned is now on Grey's Anatomy which is weird, once had crazy hair on That 80s Show. That's the best I've got.
Verdict: Magpie is for the birds. Only a bird brain would put her in a movie. A little bird told me it'll never happen. Putting Magpie in a movie would ruffle my feathers. I think that's all the bird puns I've got. And my apologies to anyone who suffered through that.
After The Scarecrow, Ra's Al Ghul, The Joker, and Two-Face, who should be Batman's next enemy in the Batman Begins/The Dark Knight series? Well, as of now we know that Tom Hardy will play Bane and Anne Hathaway will play Catwoman.
Check out the master list for all the villains covered. I've pretty much run out by now. Obviously, there are more Batman villains, but not any of significance that I know of. As of February 2009, no one is confirmed as a villain. Not the Johnny Depp Riddler, not Phillip Seymour Hoffman Penguin, nobody.
