Leaton also received the 2006 grand prize Walt Disney Pictures paid internship. His mentors included some of the top executives, and he began getting hands-on experience on various Disney films. Years later when Lindsey Brookbank of the Collegiate Times asked him what his favorite memory was from his grand-prize internship, he replied "Having dinner with Roy Disney on board the Queen Mary."
