Eleanor Summerfield (Elizabeth Robson) played Sheila Wilcott in the original version, Rires au paradis (1951).
This film, made during 1969-70, spoofs the then-current obsession with the Decimalisation of the pound sterling in Great Britain. Ronnie Corbett's first scene shows him being tested by his manager in converting from the old currency to the new. He erroneously says "6 is 5 and 10 is 12 and one is one and one fifth." As an aide-memoir one was supposed to remember "6 is 5 and 12 is 10," but you then you had to halve the second number - sixpence (6d) was 2½ new pence, and 12d, a shilling, was 5 new pence. The answer to the manager's question "how much is 42½ new p?" was eight shillings and sixpence, or "8 and 6" as people would have said.
