Alyson Hannigan has always been drawn to animation, but it was her Buffy the Vampire Slayer director, Joss Whedon, who put the connection best.
“I think Joss put it perfectly when he said, ‘I feel like if we opened you up, a cartoon would just pop out,’ ” Hannigan tells PEOPLE. “I think that’s the most fitting description of me.”
Hannigan plays Winter, a gentle faun who yearns for a special ability — only to realize she was special all along. (Awwwwww.)
