Robert S. Baker: <<But by the time we came to the end of the series we were often writing the scenes in the office and sending them straight down to the floor to shoot. [...]
One of the last episodes we did, Island of Chance, Harry [Junkin] was practically finishing off the script as they shot it downstairs. In the story the three characters were wandering through caves and one of them says, 'What's that I smell?' I wrote back, 'It's the script!' gave it to Harry and he cracked up.>> (Simper, p.21)

Leslie Charteris, 6th October 1966: <<Frankly, this read to me like the kind of farrago of lurid nonsense and hackneyed maneuvers that any writer in search of a potboiling assignment could slapdash out in half an hour with the aid of a couple of highballs.>> (Barer, p.145)
Leslie Charteris, 13th January 1967: <<The script of "Island of Chance" has eliminated, thank heaven, most of the outright garbage which I indicated in the synopsis. [...]
No snake goes looking for trouble, and anybody who counted on one to perform a murder for him by seeking out and gratuitously attacking a sleeping human would be as optimistic as if he relied on a bee released in the same room to sting a man. [...]
With everything fixed up, this show may drag itself up from the original trash to the dizzy heights of average TV mediocrity.>> (Barer, p.148)
