1975 film
- Retroactive Recognition: Dietz is played by Anthony Ainley, who would go on to play The Master (no, not that one). Also Hilarious in Hindsight, considering he's the third Master to appear on Mystery Science Theater 3000. And doubly so since The Five Doctors would later get a Rifftrax treatment.
- They Wasted a Perfectly Good Plot: During World War I a bunch of British sailors board the German submarine that sank their ship, resulting in a close-quarters battle for control of their destination. There's definitely potential for a great and pulpy full story just in that setup, making it kind of a disappointment when it's interrupted by the dinosaurs.
