When Rigby spots Carwood in the hotel, Carwood is holding a hat with his right hand. On the next cut, when Rigby walks up to him, the hat is now in his left hand.
When Elizabeth visits Rigby at his hotel room to drug him, she stands in front of him at arm's length. On the following cut, which is a closeup of Elizabeth, the distance is shorter, and they are now face-to-face.
When Rigby is on the beach with Elizabeth, he has a towel draped over his left shoulder. On the following cuts, the orientation of the towel changes. Sometimes it is protruding a little bit on front side of the shoulder, and sometimes half the towel is protruding.
When Elizabeth and Rigby are talking on the beach after their swim, Elizabeth is sitting near some plants. On the following cut, when she asks him why he hasn't kissed her, she is much closer to him, and her head is resting on his arms. Then in the next cut, as he is about to kiss her, she is back to the original position.
When Rigby is out sailing with Gomez and his narration is describing the various islands, long shots of the different islands are shown as he describes them. However, when it cuts back to him between the different islands, the ocean and land shown behind him does not change.
Set in the town of Carlotta, but on Emilio's boat it's misspelled as Carlota. It's also Carlota in Rigby's telegram draft at the beginning. But in the town's fiesta fireworks display, it's Carlotta, presumably definitive.
When Rigby is out on the boat fishing and snags a big swordfish, the spinning sound of the reel line can be heard and the pole is seen to be going back and forth sideways; however, the reel line does not move. It stays the same length. In addition, for such a big fish, the pole hardly bends.
When Rigby opens the bathroom door, Bealer is hiding behind the shower curtains with his right hand visible clutching the curtain. Then, on the following cut, he peeks his head out from behind the curtain while clutching the curtain, then ducks completely behind the curtain. These two reactions are in conflict and inconsistent with Rigby's action of opening the door. The second cut alone is the appropriate reaction.
When Rigby gets shot in the left arm while chasing Carwood, the arm is profusely bleeding, and it is hanging useless in a dead position. Throughout the following sequence of Rigby chasing him, including at the end of the film when Rigby hugs Elizabeth, the arm constantly changes between being useless and being able to function normally.
