When Mannix is brought into the hospital room in a strait jacket, the position of the water jug on the table at the foot of his bed changes from shot to shot, first being centered and then being near the corner of the table even though no one moves it. When Mannix tries to loosen his restraints on the edge of the table, he tips the jug over, knocks off its lid, and pushes it off the cloth on which it had been sitting. Then Dr. Adams enters the room and the cloth is once again smoothed out, the jug (although still on its side) is again resting atop the cloth, and the lid is back on the jug.
At the 3:00 minute mark when the camera cuts to a tight shot of the character Miss Carrie Day, (played by Judi Meredith), the shadow of the Boom Mic can be seen on the wall behind her.
