Ray Harryhausen - Earth vs. The Flying Saucers;

John P. Fulton - Frankenstein,

and the Lydecker Brothers, many Republic serials including Radar Men From the Moon.

All of their work was done on film, and I still love to watch them.

A John Frankenheimer directed black and white WWII action film from 1964, featured ACTUAL TRAINS being wrecked.
Spectacular multi camera shots of the crashes were simply incredible.

No CGI, no AI, just actual trains being crashed on purpose. They also used real dynamite to blow up a rail yard to simulate an allied bombing raid. The French Railways needed to upgrade the yard to a new gauge, so allowed it to be blown up for the film.

Well worth a watch.

Features a Bollywood dance scene atop an actual moving train, with no camera tricks or post-production manipulation. The star, Shahrukh Khan (SRK) wore no harness; it is unclear whether any of the dancers had safety equipment. The spectacular shots of the train moving thru the mountainous countryside of southern India, the dizzying shots of the group dancers, and the tactile closeups of SRK and Malaika Arora make this scene cinamatic gold. I do question the ethics of exposing actors to such danger in pursuit of art, however. Had there been casualties, the scene would not be so enjoyable, right? Thank you Uncle Joe for posting this interesting analysis. If anyone would like to check out the video, "srk dancing on top of a train" https://share.google/OLfqJX5o1IcOfHv1k
