Directed by: Seth MacFarlane
Starring: Liam Neeson, Charlize Theron, Amanda Seyfried, Neil Patrick Harris, Seth MacFarlane
Factual error: The movie is set in 1882, however there is a scene where he meets Doc Brown with his DeLorean. Back to the Future Part III took place in 1885.
Factual error: When Albert escapes Clinch's gang on the train, a marking on the boxcar indicates that its roof was replaced on 10-24. 1824 was long before this type of rail car was built, and 1924 would be 42 years after the movie is set.
Continuity mistake: When Clinch and his gang start to chase Albert, from his house, many of the sheep start running and moving out of the way, even kicking up dust. When the camera angle changes, none of the sheep are moving and there's no kicked up dust.
Edward: Hey, dude, you really shouldn't drink and horse.
Trivia: The man Clinch shoots at the bar when he first gets to town is Ryan Reynolds, who is uncredited. Reynolds has also appeared in Seth McFarlane's "Ted" (for which he was also uncredited) and "Family Guy."
