As with the other contributors, I have happy memories of watching this excellent TV drama which regularly included elements of sci fi, horror and supernatural goings-on.
It was stylish entertainment and having recently seen a couple of episodes again for the first time since the 70s, I'm pleased to say that it's lost nothing over the years which speaks volumes about its original quality.
Just one small point ...I think you'll find that it was, in fact, an American production possibly made for (or by) the NBC Network (I may be wrong and I'd be more than happy to stand corrected). Certainly, it was shot in Sydney and featured local actors in support roles. As other contributors have correctly noted, however, virtually every episode starred an imported Hollywood lead actor and the largely Australian production crew worked under the supervision of American director Mende Brown. It could, and perhaps SHOULD, be more accurately described as an American /Australian co-production.
Anyway, the final product was a highly watchable example of 70s television. Unfortunately, and sadly, it sank like a stone and disappeared quickly from the small screen. Perhaps the show's sheer sophistication may have priced it out of the mass market? Perhaps it arrived on the scene a fraction of a moment too late at a time when other quality series such as "Columbo" and "The Nightstalker" had already been given a head start ?
"The Evil Touch" deserved to succeed but fate intervened.
