Space Master X-7

Like the previous commenter I also saw this as a child, and in the spirit of his well written comments, I will add it was at the old Nile Theater in South Minneapolis. I was about 10. I had nightmares about this film for many days after, and to this day 50 years later, I still remember the title! Definitely not for the discerning adult, but my sci-fi grandson would love it! Solid 8 rating for the memories and thrills. However, it is only marginally acted. The special effects are good, and the airplane scene mentioned is thrilling. The oozing through the vent duct in the lab will remind you you are not safe even in your own home. I'd sure like to see this again!
