Prisoners of the Lost Universe (1983)
Let me start by saying that this is not a great movie. In fact, it may not be that good. Really, it is just a typical low-budget Sci-Fi / Fantasy flick from the 1980s. The acting is so-so, the plot outlandish, the effects are bad and the script is laughable (actually it may possibly be the high point). However, it is actually pretty entertaining when you get past all of the flaws and in the end, it is what it is… A cheesy fantasy B-Movie and nothing else.
