Producer - CNN Lost Disney Film

Missing for nearly 90 years, archivists at the British Film Institute have rediscovered a long-lost Walt Disney film called "Sleigh Bells" from 1928. It features Oswald the Lucky Rabbit, the predecessor to Disney's more famous creation, Mickey Mouse. Found among the one million titles held by the BFI, CNN's Kellie Morgan reports on the film's discovery ahead of its 'new' world premiere in London.
