Visible crew/equipment: After Magnum walks out of the guesthouse brushing his hair, in the next shot Detective Kaio is standing alone on the grass by the garden wall, with nothing particularly noticeable on the ground. In the next shot, as everyone else joins Kaio, now notice all the small branches/stones which are strategically placed on the grass to mark all the actors' positions, especially the two branches placed as a "T" where Magnum stands.

Visible crew/equipment: In the study, when Magnum tells Higgins that he opened the front gate for Rick and TC, Higgins then reminds Magnum about the poet who'll be staying at the guesthouse. Then Magnum walks over to the desk and we can see the actor's white tape mark marking the spot where he sits (it's gone when he stands up later). (00:37:35)
