Yes, I know I typed Dr. Who and not Doctor Who. That's because this isn't Doctor Who. These are the Dr. Who movies from the Sixties starring Peter Cushing. In this version, he's just an old man with the actual name Dr. Who, a doddering old scientist who built a Tardis in his garage with his granddaughter. There are still Daleks though.
Anywho, the two films, Dr. Who and the Daleks, and Dr. Who: Daleks - Invasion Earth: 2055 A.D.(yes, that's the real title) were taken down a while ago for reasons unknown. I asked RiffTrax about their eventual return, and I was assured it would happen. And it did!
Both of these films have outstanding riffs! I recommended them back when they were available a few years ago. I suggest that you check them out immediately, just in case they roll down a ramp and explode again.
