Flower power, como una regadera

This movie was based on inmates of Her Majesty's Prison Leyhill, which is located in the Cotswolds.

After the men lose the competition, they are invited to meet Her Majesty, and one of the officials says "Yes, HRH!" HRH stands for His (or Her) Royal Highness, which could mean Charles, William, or another of the Royal Family other than the Queen. The Queen is addressed as "Your Majesty" (or "Her Majesty," which is abbreviated HM).

There are two versions of this film. If you look at the Amazon (not IMDB) page, you will see that one version runs at 1 hr. 26 min., while the other is 1 hr. 31 min. Among other differences, they use different music for the last scene (when the three prisoners are walking over to see the Queen): in the longer version, they use The Staple Singers' "Heavy Makes You Happy," while in the shorter one, they use Elton John and Bernie Taupin's "The Power" (this difference is reflected in the music credits at the end of the film). Also, in the longer version, when they stop outside the formidable looking gate, there is a rear, long distance shot of them, and you hear Colin say, "I hope they let us out," while in the shorter version, the shot changes to a mid close-up from the front, and he says, "A bit of advice, lads. Don't forget to curtsy."
