Continuity mistake: In the scene where the Spaniard is beating up all the guys that Maverick paid off he ties one guy's neck to a post with his whip. As the shot changes you see the whip go only around his neck, but in the last shot of the scene it's around neck and post again.
Continuity mistake: During the first scene when Maverick is being hung - the Spaniard drops the bag of snakes - in the next long shot there is a hat on the ground at the hoofs of the Spaniard's horse which mysteriously disappears in the next camera shot.
Other mistake: In one of the final scenes where Maverick is having a bath/sauna, enjoying his victory, you see a man walk past with only a towel on. As the man climbs the stairs, his towel opens a little bit and you could see he is wearing white underwear or briefs. In those times that kind of underwear did not exist.
Continuity mistake: When Annabelle tells Maverick that she is short of $4000 to enter the big game he goes and extorts money from the Russian Duke. When he hands it over to her he holds a small bundle of bills, but when the camera angle changes the money is fanned out. Plus, when you pause the DVD you can count only eight $100 bills.
Continuity mistake: When the final game first starts you see a waiter walking to the commodore's table with 4 glasses of wine on his tray, the camera angle changes to a closeup of the table and you now see the same waiter with an empty tray picking up empty glasses. The camera angle changes to another perspective of the same table and you now see the same waiter delivering those original 4 drinks.
Visible crew/equipment: In the scene where Mel Gibson tumbles over the cliff, right along his boot, which is in the air, a safety harness is visible on Mel Gibson, which is best viewed in slow motion. (As per MM's rules, slow motion is permitted in order to view significant things such as crew/equipment and revealing mistakes.)
Revealing mistake: In the scene where Maverick is 'taken away' to get his hands chopped off by his Indian friends, there is a vehicle driving down a highway in the distance. It can be seen in the far background, but it is obviously an automobile.
Other mistake: During the scene when the trio is attempting to rescue the mission women's money, Maverick goes on a rant on how he is outmatched in bullets when set up against the thieves. He complains that he only has six, so he takes Ms. Bransford's gun as well, yet when the shooting finally begins, he fires about fourteen shots from his six-shooter before pulling out his second gun.
Continuity mistake: When Maverick walks into his room at the beginning of the movie after playing poker, he doesn't shut his door, but it is mysteriously shut when Anabell knocks on it a couple of seconds later.
Continuity mistake: During the scene on the paddle boat with Bret Maverick (Mel Gibson), Annabelle Bransford (Jodie Foster), and a third character (the law enforcement type), when the camera switches from Maverick to Annabelle and back multiple times, you always can see part of the paddle wheel. It's rotational speed is significantly different depending which camera is used.
Continuity mistake: In the stagecoach when Maverick feels the driver's right hand and says he's dead. He climbs out the window of the coach and the driver's right hand is back in his lap holding the reins.
Character mistake: After Maverick gives the "actors" their hundred dollars, he says "News travels fast in the Old West." Why would he refer to the west as "old" when, for him, it's the present? This is an expression that didn't come about till later on, when the west BECAME old.
