Continuity mistake: After Johnny learns of his last rescue's death, when he enters the hallway the treatment room beside the nurses' station is treatment 4, but when Brackett and Early pass the nurses' station to go save a rabbit from a sousaphone, it's treatment 2 that's beside the nurses' station. Then, as soon as Brackett and Early enter their door, in the next shot as Dix speaks to the officer, it's treatment 5 beside the nurses' station.
Visible crew/equipment: In the opening scene where General Clayton is explaining the 4077 to the psychiatrist, the scene changes to the outdoor set and the camera pans to the right. As the camera pans past the hospital, a white 1970s era shuttle van can be seen driving into the set in the upper right corner of the screen. (00:01:35)
Visible crew/equipment: When Jim-Bob delivers Betsy's mail she's washing her hair outside, and as she flips her wet hair back we can see the microphone under her halter top, while her arms are up. Then when she walks toward the cabin with Jim-Bob, the bulge of the mic transmitter is visible at the back of her shorts. (00:06:20)
