* TheOtherDarrin: If you count the flashbacks to ''Film/SilentNightDeadlyNight'', Ricky is played by at least five different actors throughout the film. Hilariously, the twelve-year-old Ricky from the sequence where he is adopted by the Rosenbergs looks younger than the Ricky who appears in the final scene of ''Film/SilentNightDeadlyNight''.
* TheOtherMarty: ''Part 2'' reshot some of the sequences that Ricky had appeared in during the first film, since the actor that originally played him was too old to reprise the part. Unfortunately they didn't do a very good job of it, with the result that the actor playing the young Ricky often changes ''in the middle of a scene''.
* RecycledSoundtrack: Music from the 1983 film ''The Alchemist'' is reused.
