I saw the Tv serial as a child, no actual memory, read the books later, I saw the dismissal review by Matthew, and wonder if I might agree with him today, but when it was a TV series it was different to anything else. Other shows TV Detectives this wasn't a hunt and capture show but hunt and execute, they were the jury, I seem to remeber them debating who they were pursuing?
The Four Just Men were hunting War Criminals post WW2, but in the books they were Balkan refugees who were taking revenge for both sides of the turn of the 19/20 century struggle there.
Remeber Winston Churchill had been involved in the Sidney Street seige in 1905, maybe that was Edgar Wallace's starting point for the story of revenge and retribution seekers?
I have speculated that maybe the story line could be revised and modernised for the latter-day struggles in that region of the world and how would it change? Computers, mobile phones, transport ect, but would it be squashed as unPC?
Bruce Willis, Steven Segal, muscels from Brussels actor (his name eludes me) and a woman as the comtemporary fourth memeber. Hopefully it would not be a new vesion of the Zoo Gang, a good idea but the roles played by actors too old to be beliefable.
