I couldn’t get into MMPR too much as the gimmick of replacing the Japanese actors was bloody obvious. I had grown up with the likes of Ultraman and Jonny SokKo and His Flying Robot more or less intact in their English dubs.
Night Flight had already aired Dynaman a couple years before MMPR came out. It was a Super Sentai show dubbed ala What’s Up Tiger Lily? into a comedy, with a rocking 80’s soundtrack that almost guarantees it will never see a home video release. Interesting that MMPR never used footage from it.

I wonder if George ever thought about Luke and Vader battling with giant robots? 😉
