Tony Pritchett's The Flexipede was completed in October 1967. It is possibly the first character computer animation telling a story worldwide, certainly in the UK. And it had a soundtrack.
Tony Pritchett died on 28 August 2017.
Kate Sullivan is currently working on an innovative multimedia project which documents Tony's work. Amongst the archive was a tray of punched cards that included the Fortran program that ran on the Atlas Computer at the University of London in October 1967 generating an IBM magnetic tape that was run on the Benson-Lehner microfilm recorder at Culham Laboratory to generate the 35mm film.
Kate, David Duce and Bob Hopgood took the deck of cards and generated various resurrections of The Flexipede.
These are described in a paper at http://www.chilton-computing.org.uk/acl/htmls/flexipede/flexipede.htm.
