One Time Travel movie that always gets stuck in my head for multiple reasons is Final Countdown. Before 9/11 Pearl Harbor was undoubtedly the worst military tragedy ever to befall the United States, and to find yourself back in early December 1941 in the Pacific Ocean with a fully equipped modern aircraft carrier and have the decision available to attempt to stop that tragedy and potential tens of millions of deaths from happening was a very powerful concept to me. Plus I like the song Final Countdown and there were some pretty big name actors in the movie.
