Keith Michell (Henry VIII) and Bernard Hepton (Archbishop Thomas Cranmer) are the only actors to reprise their roles from The Six Wives of Henry VIII (1970).
This film is an adaptation of the BBC drama serial The Six Wives of Henry VIII (1970) in which Donald Pleasence's daughter Angela Pleasence played Henry VIII's fifth wife Catherine Howard.
Star Keith Michell had previously portrayed King Henry VIII in the UK television series The Six Wives of Henry VIII (1970) and later in two episodes of the later TV series The Prince and the Pauper (1996).
The part of the film covering Henry's marriage to Anne Boleyn features some brief stock/agency footage of a number of British castles. A modern boat's superstructure appears briefly in the lower right-hand corner of the shot featuring a castle on a headland.
