Planet of the Apes
Like Mego, Power Records put a lot of money and effort into the Apes franchise, dramatizing four of the films (though oddly not the fourth!).
It's not a bad version of the story, except the ending, which I think is a little botched. The final moments of the film end with the sound of the crashing surf, which obviously could've been replicated here; instead we get Taylor's awkward exposition. Oh well.
