Why was Indy carrying a bag full of sand to replace the idol with?
How did he know that there was a security-pressure-device mechanism?
Was this ever explained or perhaps in a novelization?
I'm assuming it is more cinematic to already have the bag of sand with him, instead of having him pick up sand and filling the bag... this would have been boring to watch and time consuming of Indy picking up sand for a couple of minutes.
Research, I suppose. Jones and Forrestal researched the tomb but came to different conclusions. Forrestal, for example, didn't know about the light source that could impale invaders and was killed by it.
Come to think of it, why are you asking so many questions about what is basically an homage to adventure serials of the 1950s? I'm sure George Lucas and Steven Spielberg weren't asking about THOSE serials' plot holes, they just enjoyed the episodes!
they ask because the new world order is a whole new level of insane ANAL about mindless details in FICTIONAL movies. if it isn't explained INSIDE the movie, it just is. and is nothing to over think
He was trying to put something up there that would be the same weight as the idol. As we see though his plan failed cause a bag full of sand is way lighter than the idol. He should have filled the bag with something heavier.
The whole point of that scene is to show that he can get carried away with excitement and be rather reckless at times. It's his whole arch that's paid off at the end, where he's learned to contain his excitement and thus saves his own life by closing his eyes.
Yes, good analysis.
But swapping them, realizing that he misread th idol's weight, thus running away immediately, would still keep all of your points.
Look, the scene is some of the greatest in movie history.
But within its narrative logic could be better.
It could have played like this:
Indy swaps.
He immediately realizes his mistake.
Excited he holds the idol, looks at it with a glorious smile, then frowns.
"It's too heavy...IT'S TOO HEAVY! Satipo, RUN!"
He takes a few steps back, trying to carefully make his way back, when the sand bag comes down and the room collapses.
So it plays like in the film.
I prefer the scene we got, but it could make more narrative sense.
Excited he holds the idol, looks at it with a glorious smile, then frowns.
"It's too heavy...IT'S TOO HEAVY! Satipo, RUN!"
He then grabs the about-to-sink pedastal to stop it sinking , then with his other hand pulls out a knife and jams it into the gap between to stop the stone sinking.
In fact he could have done that first and not bothered playing "guess the weight" at all
Ahaha, I like that trick too! Why didn't he even think of it?
But again, the real sequence is just perfection, imagine if he did what I or you suggested and there is no temple collapsing, jumping on the gap, rolling under the stone door, and above all giant rolling ball.
That would suck, if he just stops the mechanism and waltzes out with the idol and Satipo.
