Robert Hardy (The Headmaster) portrayed Sir Winston Churchill in five television series and plays: Winston Churchill: The Wilderness Years (1981), The Woman He Loved (1988), War and Remembrance (1988), Bomber Harris (1989), and Dame Agatha Christie's Marple (2004) season two, episode four, "The Sittaford Mystery".
Simon Ward was a predominantly unknown actor when he was cast as the central character of Sir Winston Churchill in this movie. Richard Attenborough threatened to quit the film if producer Carl Foreman (who didn't want Ward) didn't agree to his casting.
Although Anne Bancroft (Lady Jennie Churchill) played the mother of Simon Ward (Winston Churchill), she was only ten years older than him.
Writer and producer Carl Foreman was so impressed with Richard Attenborough's directorial debut, Oh! What a Lovely War (1969), that he offered him the opportunity to direct the film and play Lord Randolph Churchill. He declined the latter offer and then cast Robert Shaw.
Simon Ward was second choice for Sir Winston Churchill after Malcolm McDowell repeatedly declined the role.
