This film is fantastic!
Just saw it for the first time. Why hadn't I heard of this? Maybe because Tim Thomerson didn't have the star attraction of better known actors. But he was awesome.
shareTo me it feels like LAND OF THE GIANTS in reverse, in LAND OF THE GIANTS humans from Earth go to a world where the people are giants and in Dollman a humanoid who pretty much looks human comes to Earth from another world and on this world WE are the giants (relatively).
I think Land of the Giants would have been cool if it had been a sci fi version of Gulliver's travels and after 2 seasons or so instead of the show being canceled they should have gone to a planet where THEY were the giants.
