IESB spoke to Jodi Benson — who voiced Ariel in The Little Mermaid and also did the voice for Tour Guide Barbie in Toy Story 2 — about Toy Story 3.

Benson confirmed that Mr. Michael Keaton himself will be joining the cast as a Ken doll to her Barbie.

Keaton played the role of Batman/Bruce Wayne in Tim Burton’s 1989 feature Batman and its 1992 sequel Batman Returns, as well as the title role in Burton’s Beetlejuice. In recent years, the actor starred in the horror film White Noise and played Lindsey Lohan’s father in Disney’s Herbie: Fully Loaded. He also voiced Chick in Disney’s Cars.

Original cast returning includes Tom Hanks and Tim Allen as the required Buzz and Woody, along with Wallace Shawn as Rex, John Ratzenberger as Hamm, Don Rickles as Mr. Potato Head, Estelle Harris as Mrs. Potato Head, and Joan Cusack as Jessie.

The movie is directed by Lee Unkrich, who was a co-director on Toy Story 2, Finding Nemo, and Monster’s Inc. and it’s written by Michael Arndt (Little Miss Sunshine). It’s scheduled for a June 18, 2010 release.
