When Rula Lenska first enters the video shop there is a visible double take from Dennis Waterman. He had no idea is then partner was appearing in the episode until then.
Towards the end of the episode when Denis Waterman says "The feelings mutual cozzer" to Brian Blessed, he is directly referencing a 1975 Sweeney episode called Ringer in which Blessed plays a villain, Frank Kemble. In the final shootout scene of that Blessed knocks John Thaw to the ground and calls him "cozzer". Both The Sweeney and Minder were made by Euston Films.
