The Final Countdown is most interesting because they got permission to film on an actual carrier it looks so much more expensive.
One thing that was neat I thought was that the Japanese pilot did not go crazy about the newer technology--he wasn't freaking out in a stereotypical way about the future technology.
Charles Durning says "everyone knows Roosevelt wants to get into the war." That's something not often advertised.
I wonder how "mysterious" the senator's disappearance really was. I don't think the big studios would have done this movie. There is no criticism at all of the military or exaggerated depiction. No one has PTSD. The use of time travel is interesting--that it is a natural phenomenon.
This is a good one to watch with that Twilight Zone in which the tank goes back to the Little Big Horn.
If they do reboot of this one, have the carrier from the future face off against the Japanese fleet. What ruins The Final Countdown for me is they didn't do that.
