Just finished reading Graham Lord's excellent 2002 biog. of Arthur Lowe, and am somewhat surprised at the size of the repeat fees then and the ones that are still being garnered to this day!
When you take how many actors were involved and then the writers etc. it made me sit up and think My God! How much does it cost just to show one repeat?? And how long do these royalties go on for?
Two passage quotes:-
Even in 2000 Ian Lavender was still being paid between £600 and £1600 for each repeated episode, and "Arthur got six or seven times more than me" Lavender told me. "We've all made more out of the repeats than we did out of the original programmes". Laurence Newman (his accountant) confirmed it: "Arthur earned more after he died than when he was alive"
In 2001 both the BBC and satellite TV were still broadcasting prime-time Dad's Army repeats and David (step son) and Stephen (son) were still sharing Arthur's huge posthumous royalties." If the BBC repeats an episode of Dad's Army Arthur's estate would get about £1,350", Bill Pertwee told me.
