First, it's easy to access at this point if only to research: https://www.youtube.com/watch?v=ukZ0qaqpKs4 has the whole film.

Second, it's structured well for it. Plenty of long shots with only music carrying some scenes with mundane goings-on. Dialogue's spaced well for quick jabs. Characters are reliably archetypal.

Third, it's a good movie but it is what it is. Had four future Oscar winning actors in it. It's straight adventure genre pre-pulp, like Tin-Tin or whatever Indiana Jones is based off of. Ridiculously melodramatic but Saturday morning cartoon-vibed premise. (Dude steals a gem because he wants something out of the estate of his dad so he can fund his mom's lifestyle or something along those lines. The French Foreign Legion is involved.) Just the right level of special effects. (A model of the fort they find all the dead guys at in the beginning is obviously being destroyed by childrens' fireworks)

Fourth, allegedly the first showing of Gone with the Wind was like a dystopian version of a focus group showing: dude just had it play when a bunch of people thought they'd see Beau Geste instead, so instead of a two hour pre-World War II's version of Star Wars play on the screen they got Vivien Leigh for fourish hours. There's plenty to work with.
