Taylor Swift has a new movie out today (March 2). She's not seen in Dr. Seuss' The Lorax, but her voice is a star in the animated film. And she recently talked about the best part of making the movie. "My favorite part about being a part of this movie is, well, it's a completely different space that you go to in your head," she said. "Because you're in the studio, which I have done a lot, but it's very different when you sing songs you wrote, and you're trying to access those emotions that you felt when you wrote the song." As for the hardest parts of making the movie, that would be the conversations with no one. So, co-star Zac Efron was not in the booth with Swift? "You're sitting there in the booth having conversations with no one. There's no one there. We all recorded our parts in different places, so you're trying to come up with what the different characters would be saying back to you, anticipate their responses, how you would respond to that, how you would react. What people don't think about with character acting in the voiceover form, you're making a lot of sounds a lot of times," she explained.
