Visible crew/equipment: When Joe (Clint Eastwood) meets Ramón for the first time in the courtyard, they exchange a few words and then walk a short distance to a table to continue their conversation. As they walk the shadow of the boom microphone is cast on one of the pillars (the pillar with the man leaning against it and holding a rifle). (00:28:32)
Visible crew/equipment: After taking a beating, killing two guards and then setting fire to their compound, Joe (Clint Eastwood) is shown crawling away, and cast on Joe's body and the sand floor is the shadow of the camera as it pulls back from him (left side of screen). (01:13:47)
