Steve Neill is recreating the gun he made for Laserblast and then Ve Neill is going to make him up again as the alien from the start of the movie (that was him). Highlights will be on YouTube and more in depth information will be on his Patreon page.
I saw this movie once when I was young. Gerrit Graham had some good lines in it. The thing had a few different titles. Spaceship, The Creature Wasn't Nice, Naked Space, and probably a few others. I just found the whole movie on YouTube, so I think I know what I'm watching tonight.
