Well I didn't keep it as I was so irritated by its inaccuracies so can't check.
However
Corbett Family Statement in response to BBC Trust's final ruling publication 30th June 2009 regarding 'The Curse of Steptoe' gives a bit more detail:
"We would firstly like to point out that Harry’s daughter, Susannah, agreed to help the writer, Brian Fillis, after she was told that the BBC wanted to set the record straight following the fabricated documentary shown on Channel 4 in 2002 called ‘When Steptoe Met Son’. She was told that the drama would portray how Steptoe and Son came into being as well as life behind the scenes. At no point was there any mention of the drama being called ‘the curse’. Steptoe writers Ray Galton and Alan Simpson told us they “declined being involved with in the 2002 documentary as it was on the same subject of conflict between the actors, which they said did not to their knowledge exist”. They agreed to speak to Brian Fillis during pre-production of ‘The Curse of Steptoe’, and reiterated to him that there was no conflict between the actors, and told him not to make another programme to keep the myth going. Unfortunately, all the detailed factual information Susannah provided to the writer was ignored, with history being rewritten for the sake of a good story. Ray Galton and Alan Simpson have since spoken about the drama with Simon Mayo on BBC Radio 5 Live (15 January 2009). In response to the question “How accurate was it?”, Alan replied “Well, as far as we’re concerned, not at all. I mean, obviously we were with them all the years they were working, and they got on fine. There was nothing, no friction at all. They worked beautifully together.”
It also gives the family's views on the other so-called facts presented.
The one thing I can say in favour of the 'Curse of Steptoe' drama is that it wasn't as bad as 'Hancock and Joan' which was absolutely dreadful.
