- This episode aired on Disney XD in the UK before the Deathlok episode.
- This episode's title is a reference to It's a Wonderful Life Christmas movie.
- A-Bomb "confirms" he is dating Eliza Dushku during the simulation. This is assumed to be an in-series joke as Dushku voices She-Hulk.
- Speaking of She-Hulk, in the Collector's simulation she has received her law degree. This is a reference to her Earth-616 counterpart, who is in fact a lawyer.
