* HollywoodHomely: Michael, such a hopeless nerd.
* {{Sequelitis}}: The original is a hugely popular 50s nostaglia funfest. This movie has only a few characters returning from the original (Frenchy, Eugene, the principal and her assistant, and the coach. All brief roles.) and introduces Sandy's cousin Michael in some weak attempt to connect the two movies. The plot is basically a GenderFlip of the first movie's plot and the results are... well, let's just say [[FanonDiscontinuity most Grease fans like to pretend it doesn't exist.]]
* WhatCouldHaveBeen: Paramount was envisioning up to three more sequels and possibly a TV series. Would ''Grease 3'' have worked with the mid-Sixties and [[Music/TheBeatles British Invasion music]] as a backdrop? Would ''Grease 4'' have dealt with hippies? Would there have been a Seventies version, sorta like ''Film/DazedAndConfused'' with musical numbers? We'll never know.
** ''[[RecycledTheSeries Grease: The TV Series]]'' would most likely have been ''HappyDays'' [[XMeetsY meets]] ''{{Glee}}''.
