Catch Me If You Can (2002) Review
While I suspect that this movie is a bit of a fabrication because it says it was "inspired by a true story", which has to be a step below "based on a true story", there was some truth in there somewhere. We do know that Frank William Abagnale Jr. (Leonardo DiCaprio) was a con man who, before his 19th birthday, wrote millions of dollars of fraudulent checks and passed himself off as a pilot, doctor and lawyer.
FBI agent Carl Hanratty (Tom Hanks), meanwhile, is his foil, who tracks him across the country and finally around the world to bring him down. Time after time they cross paths as Abagnale goes through identities and his checks get better and better. We're watching a movie, but it's probably somewhat accurate in that the first batch of checks he passes are little more than paper with some decals on them.
