D23 reports that Walt Disney Animation Studios will be premiering a new Mickey Mouse short titled Get A Horse! at the Annecy Animation Festival on June 11. The “never-before-seen short” will feature Walt Disney himself as the voice of Mickey Mouse. “This black-and- white, hand-drawn short follows Mickey, his favorite gal pal Minnie Mouse and their friends Horace Horsecollar and Clarabelle Cow as they delight in a musical wagon ride, until Peg-Leg Pete shows up and tries to run them off the road”.
