Yeah this isn't the plan.
The plan is to get the stars in for a couple of days in front of a green screen, have them say their lines, then use "AI" to generate the rest of the scene. You want to get rid of all the labor around scouting sets, getting permits, constructing them, lighting them, feeding the crew etc. That's where a big part of the cost of making a movie lies.
This is hilarious.
Also note the possible veto from advocacy groups who oppose reopening already closed reactors. Say whatever you want about these people but I think they know more about the intricacies of nuclear power plant regulation than some johnny-come-lately startup bro with ideas of stuffing a reactor into a container.
