Minor differences in versions of this episode which air in other countries:
- "Shi'ar Imperial Palace" onscreen listing is larger, and at the very bottom of the screen.
- "Axis Of Time" is listed onscreen when the planetoid is shown following the first break, and a long pan downward showing the various stairwells behind and above Sinister is also present here.
- Bishop's harmonica theme reprises briefly as he's shown.
- "Castle Worthington, England" onscreen listing is larger, and at the very bottom of the screen.
- Same goes for "London, England".
- "Cable's Future 3999" lacks "A.D." beside it.
