As a title, ALL A CLONE BY THE TELEPHONE gives you some idea what to expect from that nonsensical story. It's a light, semi-serious story about a struggling screenwriter (gee, it's amazing how many of these episodes have the same type of character in them - writing from life perchance?) who discovers that his answering machine literally has a life of its own, leaving messages on people's phones and generally having unauthorised conversations with all and sundry.
The screenwriter tries to beat this possessed mechanism but eventually comes to love it in a twist late on. And this story isn't too shabby really - the premise is handled well, and the kooky atmosphere brings the laughs to life. It's always great to see Dick Miller in support too, here playing a typically bullish boss character.
