Predator by Bethesda. Specifically a pre game short film featuring the protagonists opportunistic brother and his fall from morality as he dwells further into human experimentation.
Fallout, but not any of the games. Instead I would something in the Style of the world war z novel, not to be confused with the piece of trash they passed of as a film version. To be precise, It would be a series of interviews of the formation of specific settlements and certain key battles and events hinted at but never shown in the games. This would be conducted by the aliens in the mother ship in fallout 3. The opening scene would be of a warhead flying thru the stratosphere before panning out to view the bombs start to fall on the east cost, before shifting to fucus on Robert House’s defense of new Vegas.
I’m not sure if you can tell, but I have put a lot of thought into the second one.
