Factual error: In most of the scenes at the craps tables, the players are holding the dice with both hands. This is a HUGE no-no in casinos and the dealers would have warned the players time after time.
Factual error: In the final gunfight, we see a close-up of Charley fanning the hammer and rapid-firing his six shot Colt Single Action Army nine times in a row. [Kostner has stated in interviews that this occurs because a short scene of him switching revolvers (he had a second revolver in his belt) was left on the cutting room floor. Still a mistake, but there's the reason.]
Factual error: When Alex first meets Emma, he claims the law firm of Van Buren, Polk, etc. is in the Prudential Tower. Yet, in the last scene where he is trying to win Emma back, you can see the Prudential Tower outside the window of the office they are in (to the right of the John Hancock tower).
Factual error: Near the end of the movie a Greyhound bus is shown. The route through Taos to El Paso is served by T.N.M. & O. T.N.M. & O. was purchased by Greyhound many years ago. However, the buses were marked with T.N.M. & O. as of a couple years ago when I rode the bus from Taos to Albuquerque. As of today greyhound.com still shows it as being served by T.N.M. & O., not Greyhound.
Factual error: During the film, there are extracts of two songs - 'The Spy' and 'Maggie McGill' - from the Doors' fifth album, Morrison Hotel. Great songs, however the film is set in 1968 and Morrison Hotel was not released until 1970.
Factual error: When Charlotte visits Kyoto she arrives by Shinkansen (bullet train) and walks along the platform past the end of the train as if she was leaving the station. The exits at Kyoto Shinkansen platforms are in the middle and not at the end. At the end of the platform is a barrier to prevent you walking down onto the train tracks. (01:14:05)
Factual error: The audition scene for Erica's play would never take place in the theatre. Auditions and rehearsals are held in rehearsal halls, not the theatre. Yet they show the sets already built and installed, lighting and effects in place, and they reference the costumes being ready. This does not happen until the show is close to opening.
