what have I gotten myself into?...
Most likely, more than you are capable of.

A microcontroller is not capable of doing an animated video. You would need a full blown processor, like an ARM for that. Raspberry PI is a good example. There are LCD screens already interfaced to it.

Depends on the type of animations... but yes.

You will need a suitable LCD screen which you are already diving into.
A Driver for the LCD screen (Unless you want to code and build this yourself)
Interface with the driver with a microcontroller or other device.
A program of firmware to send images / video to the LCD for display.

Microcontrollers are responsible for those little tamagotchi games. They can animate an LCD, but 'video' takes more juice. Fortunately, you can get some small devices that pack a whallop!

Let's say I'm using the nokia screen from my old phone: can I get a list of stuff I need? As my name implies, I don't know a lot about electronics.

We gave you a rough list further up. Not all Nokia screens are identical, if you can get a part#, then we can look into the next puzzle piece for you.

I found the specifics of the display:
Type TFT, 256K colors
Size 2.0 inches (~24.7% screen-to-body ratio)
Resolution 240 x 320 pixels (~200 ppi pixel density)
- 5-way navigation key

Well... I think this should be a good read for you :
https://www.sparkfun.com/tutorial/Nokia 6100 LCD Display Driver.pdf

It goes into great detail about how to drive a display... and might want to make you rethink what the finished product will do.
You 'can' find a way to interface this as a standard display for use with a Raspberry Pi or something similar, but you may also determine that a very simple image or set of images cycling on the display is acceptable.

It really is going to be a complex project, and you will need to take the time to learn as you go.
I'm not aware of a part-list you can buy to make this thing work right away without a serious time investment.

Oh cool. I suppose he could use a raspberry pi zero to get animationy things on a screen. Its tiny so it could easily be concealed in a pocket or something and only costs £4. The only problem is, that hes gonna be waiting a looooooong time to get one of those unless he gets one for a ridiculous price on ebay. I dont know how he could interface with it tho.

From the looks of things the OP wants a transparent LCD screen... so problem 1 will be finding a display that can be taken apart to remove the additional layers behind the LCD that are responsible for back-light and light diffuse.
problem 2 will be interface.
The RasPi have an output specifically for LCD, but I don't have any details on it unfortunately.

I think all the larger pi's have a dsi port on them for screens but not sure about th zero. It does have mini hdmi tho. And he will need a battery to power the screen and pi.
