* ActorAllusion: Creator/ChristopherWalken plays [[spoiler: an [[Film/TheProphecy undercover (arch)angel]]]]. [[WordOfSaintPaul Walken has said]] that when he read the script, he decided that [[spoiler: Morty and Gabriel were actually the same person, and played Morty accordingly]]. If you watch the two movies back-to-back, it's impossible to miss: [[spoiler: [[CallBack "It's time to come home."]]]].
* DawsonCasting:
** Played straight with Creator/JonahHill, who portrayed the 17-year-old Ben at age 21.
** Averted with Lorraine Nicholson, who portrayed the 14-year-old Samantha and was only slightly older at age 15.
** Inverted with Katie Cassidy, who portrayed the 27-year-old Samantha at age 18. Cassidy was notably younger than Hill, despite playing a character who was supposed to be 10 years older.

* RecycledPremise: The concept of a universal remote control was [[OlderThanTheyThink done before]] in ''ComicBook/{{Buster}}'' strip ''Vid Kid'', where the title character used his remote to solve [[MundaneUtility everyday situations]] with often disastrous results.
** Not to mention an episode of ''Series/{{Goosebumps}}'' [[NamesTheSame of the same name]] (which itself was adapted from a short story from one of the anthology books).
* ThrowItIn: As mentioned above, Creator/ChristopherWalken personally decided that [[spoiler:Morty and [[Film/TheProphecy Gabriel]] were the same person]].
