Anna Faris, Christina Applegate and Amy Poehler are the speaking voices for Jeanette, Brittany and Eleanor.
"The sound of their voices makes kids crazy," said Poehler.
The actors enjoy being part of a film aimed at a young audience.
"You know, it's their movie. They get to have this movie. It's like a concert movie for them and I think that's fantastic," said Applegate.
And Zachary Levi, who's left in charge of the Chipmunks for the "Squeakquel," loves the idea of having young fans discovering his work.
"It's a really cool blessing, you know, I mean, you never know. I mean, at 3 years old, they're not going to be like, 'I love that Zachary Levi.' They're going to be like, 'That guy's funny.' Or, you know, whatever. Apparently that's the Chipmunks talking," said Levi.
And if you have ever wondered how they know their eyes are in the right place, Zachary Levi has the answer.
"We're looking at thin air. We rehearse with little stuffed animals so you kind of get a feel of how big they are and where they're at," said Levi. "And then they take those out and you're just kind of, you're just staring into space and talking to yourself."
"Alvin and the Chipmunks: The Squeakquel" is rated-PG due to a little mild rude humor.
This "Squeakquel" was clearly made for mini-sized moviegoers. Small children will probably love it and their adult chaperones can take comfort in that.
