My girl Effie is a diva after my own heart (before she's even famous, she turns down a paying gig becuase she "don't do 'oohs' and 'aahs'.") and that MLK line will never get old.
McDormand's Jane feels like a lot of the divas I personally know (my mother, my friend Christi's mother and grammy) when she grumbles about the awful service in that restaurant.
She scares to shit out of everyone and will stop at nothing to get what she wants. I wanted to sign up for the "Miranda Priestly School of Bitchiness" the minute she first evily glared at Anne Hathaway's Andy.
He steals scenes better than anyone I've ever seen and the way he is such an asshole to everyone (love that "Don't you know any fucking Shakespeare?" line to DiCaprio in the beginning) is a lesson for every diva in training.
Runners Up: Annette Bening brought her whole diva aura to Running With Scissors and made it a much better film than it should have...Fiona Shaw was so over-the-top in The Black Dahlia and, consequently, so hilarious, that she almost made Faye Dunaway's Joan Crawford seem subtle...Julianne Moore made a real diva entrance like the true pro that she is in Children of Men.
