The actor who played Mr. Blessington (Patrick Newell) also played Inspt. Lestrade in Geoffrey Whitehead's Sherlock Holmes TV series just a few years earlier.
@Theta101 The actor is Nicholas Clay - he is in another Sherlock Holmes, but with Ian Richardson as the great detective- in Hound of the Baskervilles. Also he is in the film Excalibur with a young Helen Mirren. Unfortunately he is no longer with us.
If you think about it, Blessington probably ended up with about a quarter of the money himself; after all, he was paying for the supplies, groceries, servant salaries, etc out of his three-quarter share.
@xihakuix Not at the beginning, about mid-way through... I've found that's the case with some of the videos on RU-vid uploaded as such... Oh well, I'll take Holmes, even out of sync...
