Can anyone explain how fast should the internet be for Chromecast movie playing?

Hi, I'm really new to the Chromecast technology, and most especially the laws of internet/bandwidth physics (if there ever is such a thing). So I hope the Chromecast/internet geniuses here can help enlighten me through careful words and deep explanations how it works.

So I'm flabbergasted with Chromecast, I really am. To think that this technology has been available for 3 years makes me feel like an ***** for those 3 years. Just want to ask, how does it work? And how fast should my internet be to be able a movie NOT BEING STREAMED, I repeat, not being streamed, but instead saved to a local drive (maybe a phone memory, a hard drive or what) to my TV?

To add to some knowledge I was able to read, it may seem that you only need even 500 kbps to run a movie locally saved to your drive. Is this true? The guy's reason for saying this is the movie is shared on the "local bandwidth" and is not coming from the internet or whatever that is why even the slowest internet can play 1080p or 2k locally saved movies thru the Chromecast without lags. Like it just used the slow internet to start up the engine. Whatever that means. My reason for asking, is I travel a lot. From here to Asia. And a lot of these "modern" hotels do not have a simple TV that has a working USB port to have my legally bought movies (of course) play during the course of my stay. I have around 2TB worth of portable hard drive with movies/series, yet MOST and I mean most of these TVs either do not have a USB port, or if it does, does not accept hard drives (I'm not even sure what's its use then), or even some only accept about 64GB USBs, do not know why is there a hardware limitation at all.

So now I bought this Chromecast, but the thing is, I have a fast internet so I really can't test it out until my next trip, which is a month from now. And you know how unreliable hotel internet is. I really want to feel prepared, I do. Like bring my hard drive, Chromecast, and finally get to watch my missed shows after each business meeting.

So how does it work? Is it true that even a very slow internet can play high-res movies just as long as it is saved on the phone casting thru the TV?Why is it like that? I mean, it may be locally saved, but there may be some weird technicality that, IT IS a big movie anyway and no matter how locally stored it is, be it thru a phone, or a hard drive movie connected to a laptop, it's still that big to fluidly stream to the Chromecast. Can someone explain this technology or debunk the theory? I reiterate that I am not streaming, but instead, playing a movie stored in my S6 Edge, and hard drive, casting thru the Chromecast.

And one other thing, will it use the same amount of data as much as the size of the movie? Like casting a 4GB local movie stored on my phone use up about the same data? Or maybe near to it? Or almost nothing at all? And any explanations why?

Apologies for my ignorance, really just needing answers to make my experience worthwhile, and hopefully, prepare me before my trips. And apologies for my long post. Just that excited with the device I guess.

Thank you all!
 
Chromecast doesn't save to local drives, so the question doesn't make sense. It's used to mirror your phone's screen to your TV. (Any router sold in the last 10 years is fast enough - 1mbps should do it.) It's not the internet speed that Chromecast uses, it's your LAN speed - the speed from your phone, through your router, to your TV. If the router is connected to a 128kbps internet connection, it will eventually finish downloading its updates, then it'll work fine on that 150mbps router (which is only running 150mbps between devices connected to it, not through the internet).

(As for size, if it DID download movies and save them, a 4GB file is 4GB in size whether you stream it, save it, download it using Chromecast [which you can't] or your phone.)
 
Thanks for the fast reply. And I didnt mean that Chromecast saves to local drives. I mean let's just say I have my S6 Edge. ! movie is saved in it, let's say Magilla Gorilla The Movie. Then I cast this movie (using Localcast app) to my Chromecast. So there we go. Saved in my phone. Not streaming (e.g. Netflix, YouTube, etc.). So like how much speed will it use, how much data will it consume on my mobile data, given that it is already downloaded in my phone and not being streamed thru some streaming site.
 
If the movie is on your phone already, you would not be using any mobile data, just local wifi.
 
However, you may have issues getting your Chromecast to work on a hotel's WiFi, most of which require logins, and most of which also disallow direct connections between WiFi devices on the same SSID.
