All I remember about it are these few things: Pretty sure it was made in the 80s or mid - late 70s.There were scenes where (I think) a team of thieves were breaking into some big castle thing that had those laser security things where the thieves had to carefully slip by the cris-crossing beams. The climactic end involved a man and women who were part (I think) of the team of thieves. The man was transforming into some sort of monster or something and the women was crying and begging for him to keep his humanity. I think that he ends up sacrificing his life to save her and or the rest of the team. The very last shot as the... See Morecredits start to roll is of a patch of earth or bog or something that seemed to suggest that the story wasn’t over for some reason like the monster wasn’t all the way dead or something. I know that these are vague, cliché factors that are in a million movies but does anyone remember one with all of these?
