About halfway through the episode, when McGarrett is speaking with Philomena Underwood (Geraldine Page) at her dig site, his arms are separated from his body when the shot is taken of him from the front, as though he had his hands on his hips, but in the reverse angles taken from behind him, his arms are hanging down, directly against his body.
Near the beginning when Steve walks into his office and picks up the ringing phone, the receiver is sitting on the hook backwards so that Jack Lord can pick up the phone from in front of his desk without having to perhaps awkwardly turn it around before talking.
