* ActorAllusion: Christopher Walken plays [[spoiler: an [[Film/TheProphecy undercover (arch)angel]]]]. [[WordOfGod 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 Jonah Hill, 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.
