Alert regular Kenneth Morgan has a good suggestion:

CT/RT/MST Double Features: Come up with a double feature comprising one title from Cinematic Titanic or RiffTrax and one title from MST. I have two possibilities: first, “The Magic Sword” from MST and “Jack the Giant Killer” from RT. Both have similar tones and storylines, both feature over-the-top villains and less-than brilliant heroes, and both are actually pretty good, if pretty goofy, movies. Second, “The Leech Woman” from MST and “The Wasp Woman” from CT. Both feature women of a certain age who use less-than reputable means to retain youth and beauty, but pay for it big time.

I’m going to open it up even further and allow CT/RT double features, like a Don Dohler double feature of CT’s “The Alien Dactor” and RT’s “The Galaxy Invader.”

Would would you pick?
