I was watching a little potboiler called “Ground Zero” (1973) on Roku this morning. The final scenes had a bad guy with an atomic bomb at the top of the Golden Gate Bridge (pretty crappy movie, but damn good location shots for the interior of the bridge), and a couple of good guys trying to stop him before the bomb goes off. While one good guy chases after the bad guy, the other good guy is trying to disable the bomb. Cut to an exterior scene of traffic crossing the bridge while pleasant music is playing and…the movie ends, at least in the cut of the movie I saw on Otherworlds TV.
Did the movie actually end abruptly like that, or was there another scene?
The version available on YouTube does have an additional scene and the film length (83 minutes) matches that given on Wikipedia. I checked because the final scene (Stock nuclear detonation footage) on YouTube could have been tacked on by anybody. I like your ending better.
But wait! The Spanish version (89 minutes) ending has a third option: The heroes save the day!
According to the You Tube write up the movie had three (or more?) endings, all of them bad. Thank you!.
Trivia note: This movie was created by the same Flocker brothers who made Curse of Bigfoot (1975). The story on that movie was that brothers had mad a short film in 1963 about a group of high school students who went on a field trip, uncovered an unknown mummified froze creature, which later thawed out. And, as we all know, mummies can sometimes wake up with quite an attitude. I don’t know that the original film ever saw the light of day, but by the early 1970s, Bigfoot movies were quite a thing, so the Flocker brothers filmed a new intro where a cryptozoologist (played by one of the Flockers) tells the story of the ill-fated field trip, where we see the original film as a flashback. A Bigfoot-type creature does make a cameo appearance in the new footage, and I guess that’s where we’re supposed to infer that the mummy in the flashback was supposed to be a Bigfoot.
One other tie-in to Ground Zero, the bad guy in Ground Zero plays the teacher in the new footage of Curse of Bigfoot.
