Police Surgeon is a television series made by ABC Weekend TV and starring Ian Hendry as Dr Geoffrey Brent.
Sydney Newman had reservations about this concept but supported the creation of the series and Bond cast Ian Hendry in the lead role.
A generous commercial deal had been struck with the police surgeon who was the inspiration for the series and had financial and creative rights in the series, aside from the script writing and just before the first episode was to be transmitted legal action was threatened by this individual, unless he could write the scripts and ABC television's legal department became involved.
It is possible that the reason for this was the legal and financial disputes surrounding the original concept, as The Avengers appears to have been devised as a hasty replacement that could also serve as a vehicle for its star, Ian Hendry.
Guest actors who appeared in Police Surgeon include Michael Crawford, Bernard Archard, Harry H. Corbett, Geoffrey Palmer, and Nigel Stock.
