* BTeamSequel: Not only did Creator/JohnTravolta and Olivia Newton-John not return, but director Randal Kleiser and writer Bronte Woodard had no involvement.
* DeletedScene: Several scenes were cut from the film, including:
** Frenchy trying to help Michael become a "cool rider".
** Michael talking to Stephanie and comforting her after the talent show.
** Goose accidentally slamming a door into Rhonda's nose.
** Davey helping Dolores stuff her bra at the luau so that she can be dating material for him.
** A sequence at the very end where Michael and Stephanie fly off into the sunset on a motorcycle, similar to the ending of the first film, where Danny and Sandy fly off into the sunset in a car.
* FranchiseKiller: The failure of this prevented further {{Sequelitis}}. There were studio plans of having at least [[WhatCouldHaveBeen three more sequels and a TV series]], but they were instantly scrapped after this film bombed.
* HostilityOnTheSet: Maxwell Caufield and Creator/MichellePfeiffer didn't get on at all. He found her stuck up, while she thought he was full of himself.
* OldShame: Creator/ MichellePfeiffer joked that she showed the film to her kids and they turned it off after twenty minutes. While filming ''Film/{{Stardust}}'', Creator/MatthewVaughn told her that this was his favourite film of hers, her response was a FlatWhat.
-->I thought he was pulling my leg...It was my role in ''that'' that made him want to work with me.
* StarDerailingRole:
** Maxwell Caulfield blamed this film for killing his budding Hollywood career. After the movie bombed, Paramount dropped his contract. In his own words, "It took me ten years to get over ''Grease 2.''" (He did find relative success on the ''Series/{{Dynasty}}'' spin-off ''Series/TheColbys'' only three years after this film.)
** Creator/MichellePfeiffer's career nearly suffered this because she was initially considered to be rejected from working on ''Film/{{Scarface 1983}}''.
* WhatCouldHaveBeen:
** Creator/{{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 ''Series/HappyDays'' [[JustForFun/XMeetsY meets]] ''Series/{{Glee}}''.
** Creator/TomCruise auditioned for Johnny Nogerelli, but director Patricia Birch wanted someone older and taller.
** [[Music/TheBeeGees Andy Gibb]] was initially going to play the male lead, but he failed his screen test. Music/{{Cher}} initially signed on to play Paulette Rebchuck, but backed out, complaining of a low salary and not having a finished script. Jennifer Beals signed on to play Sharon Cooper, but dropped out to play the lead character in ''Film/{{Flashdance}}''.
** [[Music/{{Blondie}} Debbie Harry]] was initially asked to play Stephanie Zinone. She declined, saying she was too old to play a high school student.
** Creator/JohnTravolta and Olivia Newton-John were expected to reprise their roles as Danny and Sandy, but nothing came of it. There were also plans for Jeff Conway and Stockard Channing to have a cameo.
