Thats a good movie. But I think he was referring to 'Final Countdown'

No, that's not the name of it. You're thinking of a different movie. This was a movie about a natural phenomenon - a storm - and toward the end of the film the storm came back and engulfed the ship and brought them back into the future just as the Tomcats were about to strike the Japanese carriers.
