I saw this a long time ago and just caught it on TV today. Really good movie, but, knowing it was based on a true story, there were so many parts that I couldn't help but roll my eyes at, thinking that they were just going over the top to dramatize it for a Hollywood film. Reading up on Abagnale after the movie, it's insane at how similar the script was to his real life. They even took direct lines from his public speeches and put them in the movie. Hell, there's a lot of stuff that they even left out.
I think the only major thing that happened in the movie that didn't happen in real life was him getting married before spending time in prison. Other than that, there weren't a lot of major things they added in.
That guy has to have led one of the more interesting lives that a person can live.
