In mid 1935, Lye struck a deal with
John Grierson to make a
direct animation for the
GPO Film Unit. Lye was paid £30, with his materials paid for by the GPO. Lye and sound editor
Jack Ellitt went through hundreds of records looking for music to use as the soundtrack. They selected a
beguine called "The Belle Creole" by Don Barreto and his Cuban Orchestra. After the music was transferred to film, Lye made cue marks on the sound track, which he used as a guide as he painted on the image track. It took him five days to finish most of the film. Before settling on the title
A Colour Box, Lye used the titles
Cheaper Parcel Post and
La Belle Creole. ==Release==
