When Desmond first sees the magical static on his locating equipment, the location marker is in an area on the Montana-Canada border. Later in the film, when the location marker appears again, it is in an area on the east coast.
In the party scene, Wendy's aunts take away human Stretch's coat, and don't give it back. When he comes to dance with them, his coat is back with him.
In the scene where Wendy and her aunts are sitting on the small stairs and Desmond is asking them questions in the hotel room, he changes place all the time. Now, when he's standing at the stairs and talking to them, he changes place again, after one of the aunts has said: "That's none of his business." He then stands behind them. While saying "No matter,", looks at them with only his head turned. In the next shot, his whole body is turned at them. While saying: "You'll soon be out of my hair," the shot changes and he's looking at them with only his head turned again.
During the chaos at the ballpark caused by Casper's uncles, all the hot dogs in buns that fall off the hot dog cart and the ones that fall on the members of the running crowd are still raw. They are still slender and "square-shaped" from just coming out of the package. Cooked hot dogs have a plumper, "more round" shape. Note: the CG hot dogs that fall out of Fatso's belly, as he flies overhead, have the correct shape.
