It tells a fictionalised story involving Sid James as Henry VIII, who chases after Barbara Windsor's character Bettina.
A widowed Henry VIII has a marriage of state to Marie of Normandy, the favourite cousin of King Francis I of France.
The union was arranged at the behest of the bumbling Cardinal Wolsey, who selected Marie because she is the favourite cousin of King Francis I of France.
Marie convinces Wolsey to send for the French ambassador, who tells Henry that Francis I is so thrilled with the successful marriage that he will give England ten thousand gold pieces.
He rushes to stop the execution of Cromwell and Wolsey, begging for their help in divorcing Marie and ensuring marriage with Howard, but both men cry out 'Carry on, executioner!
Harry Secombe was considered for Henry VIII when it appeared that Sid James might not have been available due to possible stage commitments.
James was making a lengthy appearance in South Africa which was cut down when he heard he was wanted for the film and arrived back in time for the second day of shooting.
The film was released on 17 February 1971, exactly 15 days after Sid James' TV sitcom Bless This House was first broadcast.
