Elisabeth Banks recently sat down to talk with Entertainment Weekly, about how to talk in the Effie voice. We all know that Katniss says the capitol voice makes a funny 's' sound , and that virtually everything sounds funny in it.

 Let’s talk Hunger Games: Where did you come up with Effie’s voice?
It’s a combination of The Philadelphia Story and Rosalind Russell in Auntie Mame.
Really?
Rosalind Russell is just amazing. It’s one of my favorite performances ever. I wanted Effie to be really theatrical. I just wanted to make sure she didn’t sound too British. She needed to be a little highfalutin.
Which fans are more intense: A cappella fans or Hunger Games fans?
I would bet there’s a ton of crossover.
Would Effie Trinkett have been in an a cappella group?
Sure. There might be a cappella groups in the Capitol. That’s probably allowed. I think the Capitol wouldn’t find that too threatening.
But not in District 12, right?
They probably do a little barbershop in District 12. They need something to keep their spirits up.
