Chenoweth, most recently on Broadway in the acclaimed revival of On the Twentieth Century, voices the role of Snoopy's love interest, Fifi.
The Tony and Emmy-winning actress recently told USA Today, "Fifi's a smart, spirited poodle and she has some great pink accessories…She's a dog, but she has this feminine way about her while still being very much Snoopy's equal."
Chenoweth also spoke about creating a voice for Fifi, who was first seen in a TV special in 1980 entitled "Life Is a Circus, Charlie Brown."
"The trick was to invent Fifi's language and make it emotional, without words. It was vocally challenging," Chenoweth said. "I used Snoopy as my guide and did a female version. And it gives a personality there."
Chenoweth shot to fame following her Tony Award-winning performance as Sally in the 1999 Broadway production of You're a Good Man, Charlie Brown. "I really did this because it's something close to my heart," Chenoweth told USA Today. "I'll always remember my history with the family and Peanuts. It seemed like the right and most natural thing to do." The new film is described as such: "Charlie Brown, Snoopy, Lucy, Linus and the rest of the beloved 'Peanuts' gang make their big-screen debut, like they’ve never been seen before, in state of the art 3D animation. Charlie Brown, the world’s most beloved underdog, embarks upon an epic and heroic quest, while his best pal, the lovable beagle Snoopy, takes to the skies to pursue his arch-nemesis, the Red Baron."
