Yes those are both nice ideas. I think SOME of the stuff in the Abyss might be TOO intense for an Indy movie, but most of it would work just fine.
What do ya'll think should be the last vision? One that would imply that Spalko is fixing to get some info that's gonna ...blow her mind. Stuff that scares her. Stuff that she almost can't comprehend. Not history related though... Not sure.
Also, something to show the fall of the Soviet Union would be cool as well.
And I'm not sure what the effect is called, but having the edges of the frame fade to black (like a dark flickering circle around the footage) would be cool too.
No takers on this little project? :)
