I saw this the very first time I saw the movie. I'm surprised it wasn't already mentioned. Near the beginning of the movie, Jeff Goldblum's character visits "Hammond" at his home. They are in Hammond's bedroom. Right after Hammond explains that he has already asked Sara to go to the island, Hammond is standing next to his bed and Goldblum is across the room. Now, look in the mirror on the dresser next to Hammond's bed. You can see the legs of the camera man in the mirror. He is wearing blue jeans. You see him step across, the camera pans a little, then he steps again and is behind Hammond. This does not take slow motion or your pause button. He is right there...plain as day!
