There is featuring the first Disney character, Oswald the Lucky Rabbit, a cartoon to be screened for the first time in 87 years.
The BFI says the re-discovery of the “long lost” six-minute movie in its archive is a “delightful treat”.
Other Oswald pictures survive but Sleigh Bells continues to be unseen since its original release.
Walt Disney and Ub Iwerks devised Oswald the Lucky Rabbit for Universal in 1927 before they went on to create Mickey Mouse.
The restoration work was performed by Walt Disney Animation Studios and the new print will be shown at BFI Southbank within a programme of Disney Christmas shorts on 12 December.
“What a delightful treat to discover a long lost Walt Disney film in the BFI National Archive and also to be able to show Sleigh Bells to a whole new crowd 87 years after it was made,” said Robin Baker, head curator at the BFI National Archive.
“The restoration of the film will introduce many audiences to Disney’s work in the quiet period – it clearly demonstrates the vitality and imagination of his animation in an integral stage in his early career.”
Andrew Millstein, president of Walt Disney Animation Studios, which oversaw the restoration, said the Oswald shorts were a significant part Disney history.
“Walt have been working with movie archives and private collectors all over the planet to research the missing titles.”
