Getting in on this before it went "viral" would have been nice, but you can't always be there at the moment of creation. The only question is whether this has the potential to be a "Downfall" type idea, applied over and over again. Probably not. The joke pales the second time it's applied to anything. On the other hand, you could do endless remixes of the trailer with other great moments of screening room reactions, of which there are . . . at least three. So, no. Forget it.
Anyway:
