- Breakthrough Hit: This film got Ridley Scott noticed.
- Doing It for the Art: The film's low budget meant that Albert Finney's fee was a case of champagne. He was so eager to be in the film that he accepted.
- Real-Life Relative:
- Referenced by...: Of all things, Armand d'Hubert appears in the 2000 AD vampire comic Fiends of the Eastern Front as the protagonist of the Napoleonic wars prequel.
- Throw It In!: During the scene where D'Hubert asks Adele to marry him, she starts to laugh. This laughter was not intentional. According to Ridley Scott, she actually has a hard time keeping a straight face since one of the horses has a huge erection.
- What Could Have Been: Ridley Scott wanted the two leads to be played by Oliver Reed and Michael York (Athos and d'Artagnan in The Three Musketeers (1973)), but the small budget and studio decisions forced him to choose from a list of less well-known but more affordable Hollywood actors.
