Since you are a fan of really bad movies, and specifically lizard ones; Dinosaurus, Planet Of Dinosaurs, Jurassic Park, Tommy Wiseau films, might I suggest that no collection is complete without having the 1961 classic - Reptilicus! Please look into this. Without hyperbole, I say it could very well be the ice-cream bunny of lizard movies. Oh yes.
Here is the trailer. Honestly, how can you Riffers not do this movie? https://www.youtube.com/watch?v=glJLn1dBoPI
Mike, Bill, Kevin, I have two magical words for you three: DANISH KAIJU! Reptilicus was made for you three to riff. I see no reason why you shouldn't be able to get your hands on the VOD rights to this movie. Please do consider it.

I remember seeing this movies as a kid when the Saturaday Night monster movies were a thing on TV.
In my area it was either Creature Feature or Chiller Theater. In fact a number of movies you guys have done on MST3k and Rifftrax I first saw on thoes Saturday night movies
Please consider this one
