Apollo 13 is a movie based on the true story of of the Apollo 13 mission that was supposed to be the third to land on the moon. There was not much interest in space flights by know as they had happened before, so they were "regular." That all changed when in mid flight there is a major problem, and their chances of making it home are slim, there are ground teams working around the clock trying to give them a solution, and the flight was aired on national TV. Jim Lovell (Tom Hanks) reports the problem to the command center in Houston by saying, "Houston, we have a problem."
