Not rear-projection in fact according to the documentary at the end. It was bluescreen. That technology was really very popular back then, although it hadn’t fully developed as you can see. The BBC used it extensively on Doctor Who (under the name Colour-Separation Overlay or CSO), trying in one story called “Underworld” to do a virtual set thing and not really succeeding.
We’ve seen something of a return to rear-projection lately with the ILM Stagecraft system, although they’re eschewing that for the Andor series in favour of actual sets and another British sci-fi staple - filming in quarries!
The DVD set with Pumaman was released in 2014. So the interview is at least 8 years old, possibly longer depending on how long it took the featurette to be made and released.
I have to say I’m very pleasantly surprised by the quality of the “surgical remaster” version. I think Joel said in his announcement that these versions will be put onto the Gizmoplex going forward too?
“Sliders” was great for a while. Rule of thumb: if the Professor Autero is on, watch; if the Cromags are on it, don’t! (watch if there’s both, probably with caution) Overall, once at the point where the actor playing the professor left, all remaining episodes aren’t worth your time.
Watching this today. First of all, I like the new spinner for the Madvertisements.
Second, the replay still has the opening jazz for 20 minutes and I am so glad that I didn’t skip over it. That tune with the MST3K theme song in it made it all worth the while.
Word from the actor is that he bailed when the stories got too silly for him to tolerate. (“A swarm of neutron stars hitting the Earth? Really? That does it. I’m out.”)
The interview originally appeared on Disc 4 (The Pumaman) of Shout Factory’s MST3K Volume XXIX, released March 25, 2014. It was one of many mini-documentaries/featurettes that Daniel Griffith of Ballyhoo Motion Pictures produced for Shout Factory’s MST3K DVD releases as extra features.
