Visible crew/equipment: Just after Lovell secures the hatch for LM jettison, and Swigert states "Okay, pyro batts look good, I don't think we're gonna have to tie those other batteries," there is a visible bearded crew member wearing glasses and a hoodie on the lower right hand side of the screen. This is only visible in the fullscreen version. (02:01:00)
Continuity mistake: When the astronauts are in space and are taking their equipment off, Jack Swigert removes his outer suit gloves then removes his white glove liners and tucks them into the floating suit glove, but next shot Swigert is still wearing the black suit gloves, and it then cuts to Swigert removing his helmet and he is still wearing the white glove liners.
Visible crew/equipment: Right after the explosion, Lovell tells Houston that they've got multiple cautions and warnings, and they've got to restart, then Swigert says, "I'm going to SCS," and he flips the switch. In the next wideshot of the trio, we can see the arm and fingers of a hidden crew member wearing a short sleeve blue shirt, who's holding up a hose at the bottom right corner of the screen. This is only visible in the fullscreen version. (00:51:20)
Visible crew/equipment: During the moon landing daydream sequence, Lovell is shown performing the typical low-gravity moon walk. The thin wires used to facilitate the hopping effect can be seen at the top of the frame, and stand out against the light metal finish of the lunar lander. (01:13:30)
