What things do you frequently see in movies that would be very unlikely to happen in real life, but are there simply because the writers don’t know any better, rather than because they wanted them there?
So I don’t mean spaceships, or police stations where all the women cops look like models, or stuff like that. Those were obviously put there intentionally.
I mean things like this: in almost every adventure movie where somebody falls off of something and is hanging over space, they end up hanging on by one hand for an extended period of time while they are flailing around trying to get back onto the bridge or the ledge or whatever.
Next time you go past a playground, go over to the jungle gym, grab an overhead bar with one hand, and see how long you can suspend your weight from it. Unless you’re unusually strong or light, I’ll bet it’s only a few seconds. Hanging from a flat surface like a ledge would be even harder than hanging from a bar, where you can wrap your fingers around it.
And I would defy anyone not starring in Cirque du Soleil to hang by one hand from a slender vertical rope for even two seconds. Your grip just isn’t strong enough.
