looking for movie title and channel?

I watched a movie on cable in a hotel about 6 weeks ago, it was about a man and a woman who went to the future as part of some experiment. In the future all the people were stupid and the 2 people from the past were treated as criminals. the guy was asked to solve all the troubles of the future because he took a test in prison and was declared the smartest person in the world. I am looking for the name of the movie and the channel it aired on. Possibly HBO or Showtime as I do not recall any commercials. thank you
