In the Scene where Hammond and the diggers are in the trailer, Hammond is talking about his island. He is cleaning a glass with water and then starts to dry it off with a white rag. It changes scenes while he is talking and in the new scene he suddenly has a pink towel instead of the white rag. It is amazing that they missed this because everything else in the scene is perfect. Besides the rag swap, you can't even tell that the two scene were filmed at different times.
