Corrected entry: In the funeral scene, a guy is playing the harmonica. There's an over-the-shoulder shot of him and you hear the music, but his hand doesn't move, and therefore neither does the harmonica, which would sound like only one note being played.
Corrected entry: When Shane has a punch-up with a bad guy in the saloon, Shane hits him twice in the face. When we see the bad guy's right fist, it has blood on it, but he hasn't hit Shane once.
Correction: The bad guy has blood on his hand because Shane hit him in the face. The bad guy fell backwards all the way into Grafton's store. While he was on the floor he used his hand to wipe blood off his face. Then he walked back into the saloon and that's when they started throwing punches.
Corrected entry: In the opening scene, a Greyhound bus drives along a road in the far distance.
Correction: This error shows up only in the trailer. All the trailer scenes were put together before fixes were made. Thus, the opening scene in the movie does not show the bus.
Bus was included both in the movie and trailer till VHS and Laserdisc. For DVD, they digitally erased it in the movie.
Corrected entry: The father of the family Shane stays with loads his shotgun at one point when the antagonistic cattle rancher shows up, and the shells he loads are red plastic. All the shells then were completely brass.
Correction: Some cheap brands of shotgun shells of that time period were made of thick, red paper. They were cheaper to make and sell, but could not be reloaded as brass shells could.
Correction: If the harmonica was not moving back and forth, that would not mean that only one note was being played. A number of notes can be played without moving a harmonica, so it would depend upon knowing what notes you were hearing and knowing if those notes could be played or not to know if there was an error here.
