Variety posted a short interview snippet with Elizabeth, and she touched on Catching Fire!
"These honours also go to Elizabeth Banks (Excellence in Acting), who returns as Effie Trinket in “The Hunger Games: Catching Fire.” She promises, “No huge surprises. Effie has a heart that grows multiple sizes. We’re true to the book. Hopefully we’re delivering to the fans. That’s what they want.” Of course, “I spent a lot of time in the hair and makeup trailer, and every day we had that ‘ah-ha’ moment.”
It's great to hear that, in Elizabeth's eyes, she feels that the Catching Fire movie is staying true to the book. We can't wait to see some of the results of all that "time in the hair and makeup trailer"!
