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).
The 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.
Keith Michell previously portrayed King Henry VIII in The Six Wives of Henry VIII (1970) and would later do so again in The Prince and the Pauper (1996).
Bernard Hepton previously played Archbishop Thomas Cranmer in The Six Wives of Henry VIII (1970) and its sequel Elizabeth R (1971).
Lynne Fredericks portrayal of Catherine Howard was a first for many in Tudor film history. Frederick was the first actress to portray Howard in a sympathetic view, Frederick was also the first actress to play Howard who was actually close to the real Howard's age, and it was also the most historically accurate portrayal of Howard as of 2016.
