Corrected entry: At the climax of the final poker game, the commodore (James Coburn) shows his cards and says, "I have two small pair - eights and eights." In the rules of poker, if you do this, then you have two pair, not four-of-a-kind. A simple straight or full-house would beat his "two pair" because of how he declared it. (01:44:56)
Corrected entry: During the scene when Maverick is delayed getting to the poker table a pendulum clock is shown. Pendulum clocks don't work on board a boat as the movement upsets the pendulum.
Corrected entry: In the final hand of the final poker game, the crooked dealer deals the Commodore four-of-a-kind, and deals Angel a straight flush. Why would the dealer, who works for the Commodore, deal Angel a better hand than the Commodore? Even though Angel and the Commodore are working together, you would think the Commodore would want to win his own tournament, and therefore have the dealer deal him the better hand. The Commodore even looks surprised when he sees that the dealer has dealt Angel a better hand than him, so it wasn't something that he intended.
Corrected entry: After the incident with the runaway coach, Maverick is walking away and Annabelle trips or pretends to trip and falls against his leg. When she does she accidentally fires his holstered pistol. It would be impossible for her to do that as the pistol a single-action revolver, which means she would have to cock the hammer (pulling it up and away from the ground) and THEN pull the trigger, also up and away from the ground.
Corrected entry: A big issue is made during the first poker game with the gunfighter and the Spaniard that Brett was watching for tells in the first hour of play while he lost. During the dispute with the Spaniard over the bluff, Brett states that the Spaniard's tell told him that he had great cards-which he did-2 aces. In that game, that is a very strong hand. Yet Brett, one of the best players in the game, BLUFFS with inferior cards. There is no amount of bravado that can explain such stupid behaviour. Its obvious the writers meant to showcase Brett's ability to read other players, but no real player would bluff knowing for a fact that the other player has a strong hand.
Corrected entry: After Maverick stops the runaway horses with the dead driver, he has dirt all over him, because he was dragged under the carriage. However, after this has happened, in later scenes, his clothes are magically clean again, even though he hasn't changed clothes since.
Corrected entry: When Bret is kissing Annabelle goodbye to become the "human sacrifice" she starts off holding the sides of his face while kissing him, as shown from the camera angle in the front, but when they are shown from the back, her hands are near the back of his head, then they are back on the sides of his face when the camera angle goes back to the front again.
Corrected entry: As the dealer stands to shake hands with Bret after he wins the second-last game to qualify for the final, watch his chair. It stays stuck to the dealer's butt as he stands. Rewind and watch Mel Gibson and you can see that he starts to giggle as does the dealer who pushes the chair to the floor quickly.
Corrected entry: When Maverick, Cooper, and the commodore are in the woods near the end of the movie, Maverick throws a gun up in the air for them to fight over but Cooper still had his gun in his holster. He was never forced to give it up so therefore he didn't need to fight the commodore over the tossed gun. (01:56:10)
