AEROSMITH frontman Steven Tyler will star in the upcoming big-screen adaptation of the Caldecott-winning children's book "The Polar Express" by Chris Van Allsburg, according to Zap2it.com.
In keeping with the holiday theme, Tyler will play one of Santa's elfin helpers.
"Polar Express" tells the story of a skeptical young boy who is transported along with other children by a magical train to the North Pole. Tom Hanks stars as the Conductor.
Tyler will also lend his trademark vocals to the film's soundtrack, which is comprised of original seasonal-themed songs, including the singer's "Rockin' Around the World".
"The Polar Express" will receive a theatrical release on Wednesday, November 10.
