The coat used by Sidney James is the same coat used by Richard Burton in Anne of the Thousand Days (1969).
This is the second time that Sidney James has played a character that was originally portrayed by Richard Burton, as well as worn the same costume. The first time was Carry on Cleo (1964) as Marc Antony.
This was the first time that Kenneth Williams and Kenneth Connor appeared together since Carry on Cleo (1964) seven years previously.
Eric Rogers' title music is based on the traditional piece "Greensleeves". (The real King Henry VIII is credited by some with being the composer of the song.)
