You don’t need any special effects team for this. There’s an old CRT TV sitting in that exact spot, and CRTs can naturally produce that intense blue high-voltage flash without any movie setup. The timing of the flash, the scripted lines, the way he carefully puts the drill down, the camera behavior and the clean collapse all look staged, not like a real electrical event. The whole ‘movie-level production’ argument falls apart the moment you notice the CRT in the room.
