Josh Hutcherson and Samantha Bee Voice Christmas Critters in 'Elliot: The Littlest Reindeer' (Exclusive)

Check out an exclusive clip and character posters for the animated Christmas movie, about a miniature horse with big dreams.

You know Dasher and Dancer and Prancer and Vixen, Comet and Cupid and Donner and Blitzen. But do you recall the most famous reindeer of all? Elliot!

At least, that's his goal in the upcoming animated Christmas tale, Elliot: The Littlest Reindeer. In fact, Elliot isn't a reindeer at all, but a miniature horse with big dreams who travels to the North Pole to compete for a spot on Santa's sleigh team. ET has an action-packed clip from the movie, above, plus exclusive posters revealing Josh Hutcherson's Elliot, Samantha Bee's Hazel the goat and more characters played by John Cleese, Martin Short and Morena Baccarin.

Elliot: The Littlest Reindeer is in select theaters Nov. 30 and nationwide for one day only on Dec. 1.
