In addition, we have exclusive video of him speaking about his character "Tugg".  Stewart also talks about working again with fellow voice actors Kelsey Grammer and Martin Short and what he finds so appealing about animation and Dorothy of Oz in particular.  Hit the jump to check out the exclusive video.  The producers of the film are Summertime Entertainment, Ryan Carroll, Roland Carroll and Bonne Radford.  Dorothy of Oz is set to arrive sometime in 2012.

DOROTHY OF OZ is an animated feature film based on the adventure books by Roger Stanton Baum, the great-grandson of L. Frank Baum. The Roger Stanton Baum books are a continuation of one of the world's most popular and beloved fairy tales, "The Wonderful Wizard of Oz" by L. Frank Baum. Produced with state-of-the-art computer graphics and the latest 3-D stereoscopic techniques for animation, DOROTHY OF OZ, the latest chapter in the Oz legacy, will be entertaining to a whole new generation of fans!

In DOROTHY OF OZ, Dorothy returns to Kansas to find it devastated by the tornado that had whisked her away to Oz. The home to which she has been so desperate to return was severely damaged, and the townspeople are packing and moving out. But shortly after arriving in Kansas, Dorothy is magically transported back to Oz.

She finds out that Oz is in trouble, and the people there need her help. Dorothy’s old friends – the Scarecrow, Tin Man and the formerly Cowardly Lion – have disappeared and Oz is in a state of decay. As Dorothy journeys to find her friends, she encounters a number of new companions and problems including a man made of marshmallows who can’t think for himself, a china doll princess whose bossiness is a cover for her fragility, and a tugboat with as many personalities as he has pieces. Dorothy must help this odd group band together against a new villain – a wicked Jester who thinks all of Oz should be under his control.
