Oh, there may be a few out there.
But even before that scene there is a lot of frank talk about sex and sexuality.
The first time I actually swam across the pool, I was given a doll by my parents.
In the film Walkabout, there was a sequence in which I swam naked in a natural rock pool in the Outback.
Despite that, the costume worn by Heather Menzies, who played Jessica 6 in the series, was very short indeed.
The ice cave sequence was actually filmed in the middle of the summer in Los Angeles.
There is also a wonderfully eccentric performance from the great Peter Ustinov, who pretty much saves the last third of the production.
He designed for films like Babes in Toyland, Spartacus and The Happiest Millionaire.
