Continuity mistake: The amount of beer in the glass during the first beer scene in the movie changes between shots. It is half full, then after a while it is almost full again. (00:16:00 - 00:16:55)
Continuity mistake: During the first shootout scene inside Candiland, when Django rolls off Leonide Moguy (Candie's Lawyer) he rolls to the right of the shot, away from the room he had just come from. However in the next scene when the door is kicked in we see Django moving and shooting from the opposite side of the room, towards the side he should already be.
Continuity mistake: When Cora and Sheba are leaving the house, they are using the left panel of the double door, opening it inward. But when Django leaves the house, using the right door panel, you can see an astragal (the seal between a pair of doors) attached to the far side of the left panel. This would have prevented the left door panel from being opened inward as Cora did. (02:38:00 - 02:39:55)
Continuity mistake: After first arriving at Candieland, Calvin Candie is explaining to Steven who Django is and that they will be staying in the big house. During this scene, cuts between Calvin and Steven show Calvin's legs alternating between crossed in one angle and uncrossed in the other angle, multiple times. The lawyer's arms also go from being crossed to uncrossed when Calvin does the introductions between Django and Steve. (01:28:30 - 01:30:30)
Continuity mistake: In the scene where Django shoots Smitty Bacall, the plough that he is using can be seen on the far left of the field and moving at a slow pace. But when Dr Schultz puts his wanted poster away, the plough is suddenly on the far right of the field having not had enough time to have turned round and moved that far.
Continuity mistake: In the scene where Schultz shoots the sheriff, as he walks away he has blood on his hand and his jacket. The blood is gone from both in the next shot and from then on.
Continuity mistake: In the opening scene where Schultz and the Speck brothers first meet, Schultz gets off his carriage and lights a lantern. However, the already lit lantern hanging from the left side of the carriage goes from lit, to unlit (or missing), and back to lit as the scene progresses. (00:05:00)
Continuity mistake: In the first shot of Stephen writing a check to the Harris Feed Co: The "i" is connected to the second "r", the numeric dollar amount is "68.00" (with the period barely visible), the written dollar amount is "Sixty Five", and in the year of the check, "58", the numbers are touching and the "5" looks somewhat like a "6." Seconds later, in the next shot, which is more of a closeup of the check: the "i" is no longer connected to the second "r", the numeric dollar amount is now "65.00" (with the period very visible), the written dollar amount remains as "Sixty Five", but the handwriting (as with the rest of the check) is somewhat different than in the 1st shot, and the year is now written as "58", with the numbers no longer touching and the "5" looking like a "5."
