When I first saw this on TV as a kid, I was really taken with the fanciful far-out concepts of a conquered Earth. For a 12 year-old boy into sci-fi, this was and is the ultimate escapist fare. I had no knowledge of the British TV series at the time so my intro to Dr.Who was Peter Cushing (playing older than he is), the movie version of the old-time traditional Doctor. I probably saw this film before the previous one "Dr. Who and the Daleks" as I was puzzled by the Doctor's recognition of his old foes, the unforgettable Daleks. Yes, who can forget those frog-like voices, warped by metallics, usually screaming for the death of humans. The British cast is really keen, especially Cribbins as an out-of-place copper and Andrew Keir as a hobbled resistance fighter. They bring a curious reality to the fantastic setting.
The picture has a decidedly British flavor and, of course, is filmed in the British countryside. Though I didn't reason this out at the time when I was a kid, it had an obviously different taste to it; I was mostly familiar with U.S. low budget sci-fi pics of the '50s and '60s at the time. The scope of the picture seemed really huge back then: London in a destroyed state, humanity decimated. There was that really cool flying saucer, looking fully functional and detailed. And there were the creepy Robo-men, in their slick black bodysuits and far-out helmets, like some futuristic Nazis or space zombies. All of this stuff really just took me over and I couldn't wait for the next time the local TV channels would run it again (not very often, as it happened). Some years later, I realized the title, 2150 AD, sounded cool, but the invasion by the Daleks must have occurred only a few years before the events of this movie, and the dilapidated buildings all looked like they'd been wrecked in the sixties. Ah, no matter. Many years later, I got the DVD and the thrill, tho muted by the long passage of experience and adulthood, is still there. They really knew how to make 'em back then.
