I have to go back to 1960, maybe I could warn JFK while I was there, eh.
Several years ago, I saw a TV movie based on this premise starring Robert Hays (probably best known as "Ted Stryker" in the movie "Airplane!"). Hays and a woman companion traveled back to Nov. 22, 1963, in an attempt to prevent the assassination of John F. Kennedy. If I remember correctly, they ended up going back 2 or 3 times. They kept going back to that day, because each time, the results of their interference set in motion events which were even more catastrophic then the original scenario. I missed the beginning, and never did find out the title of the movie. Has anyone else seen this film?
