Despite his tough-guy image when playing Ken Boon, Michael Elphick was scared of riding Boon's motorbike. "I find bikes much too dangerous. It's Boon who rides them, not me. I don't drive a car either, for the same reason, really."
According to Jim Hill (co-creator), the name "Boon" was derived as follows: "Originally called "Anything Legal Considered", we fell foul of the vogue of the main character's name being all or part of the title. Boon had been derived from an American TV series from the 1950s that William Stair and I both watched and liked. It was called Have Gun - Will Travel (1957) - a troubleshooting cowboy answered distress calls. He was called Paladin and was played by the actor Richard Boone. We dropped the E and we had BOON - a modern-day trouble shooter on a motorbike instead of a steed."
