Visible crew/equipment: When Mike slams Stan down to the floor in Health class, the grey padded protective gear that Mike wears under his pants is visible as his shirt moves up. (00:47:25)
Visible crew/equipment: Before the start of the last basketball game, when Ned calls out, "Jane!" for the third time in the shot facing him as he tries to pass someone, the actors' green T-mark and three other tape marks - one yellow and two red - are visible on the floor ahead of Ned. (Visible on DVD fullscreen.) (01:29:40)
Visible crew/equipment: When Mike satiates his hunger in Ned's kitchen, just after Ned says, "That's your can now, we'll label it like that," the reflection of a crewmember moving around is visible in the cabinet's glass pane, to the left of the screen. In the other shots of the same angle we don't see movement, so we know it's not Mike's reflection. (00:40:35)
Visible crew/equipment: When Mike is in the bathroom (before he sees Alex taped up) on the cell with Ned, in Ned's two close-ups the reflection of equipment moving (likely the boom) is visible behind him between his head and feet, as he lies on the couch. (00:34:50)
Visible crew/equipment: After Mike and Alex get home, when Scarlet walks in and asks Alex how the tryouts went, the tape mark is visible on the floor in front of Alex, while he's sitting. (Visible on fullscreen version.)
