Continuity: During the firefight in the detention corridors, the blaster holes in the metal wall Jenna's firing toward keep changing, sometimes disappearing altogether. One of them is created twice, appearing as the troopers duck out of sight, vanishing and then reappearing in the same spot when Jenna fires again.

Visible crew/equipment: When Blake and the landing party are on the flight deck, preparing to go down to the planet, something black intrudes on the left side of the screen during a shot of Avon on the flight couch.

Visible crew/equipment: Ah, the hazards of shiny metal set walls. When the doctor closes Avalon's cell door, there's a hazy but discernible view of the camera and a moving film crew member.

Revealing: When the fight begins in the detention block and the trooper runs away from Jenna down the hall, two large blaster holes appear in the wall he runs toward - before the first shots are fired.

Revealing: As Jenna leaves the flight deck and heads down the access corridor, a camera is briefly visible just to the right of the hexagonal entryway.
