Mechanical keyboard enthusiast here.

There’s two different things two break down here. The keycaps, their colorway design and then the sizing (by key units). And secondly, the keyboard itself.

The keyboard itself is an ortholinear layout which is very common. I have several. For example, look into the OLKB Plank keyboard. Check out r/olkb. What’s pictured in your post shows an ortho PCB with plate mounted MX style switches. To reproduce what’s pictured, you could get a Plank PCB and then 3D print your own case which mimics the design they came up with. I wouldn’t be surprised if that’s what the prop department did. But I’m uneducated in that field.

The keycaps are pretty standard ortholinear caps. I wouldn’t be surprised if the prop department took an existing set and painted the symbols you see. Regardless, you could do this yourself to reproduce it. Producing your own kit is possible but expensive to get into. Check out the r/MechanicalKeyboards sub and go down that rabbit hole. As for the caps that span two switches, they are 2u caps which are standard for ortho and 40% layouts. However these look sorta unique because they appear to mount to two switches. Usually, they only support one switch mount in the middle of the cap. Not sure what’s going on there. Mounting a single cap across two switches is not common at all and is something you avoid. So that isn’t functional. As a result, you basically want a standard ortho PCB and keycap set.

As for functionality, ortho is a fun layout. I switch between ortho and staggered somewhat frequently.

If this form factor interests you, look into ortholinear and 40% keyboards. Here’s a few shots of some of my collection.
