I did a similar thread about this (with TV), but it is ten years old, so I will start a new one:
Grease 2 (https://www.imdb.com/title/tt0084021/?ref_=tttr_tr_tt):
I will start with this because I watched this last night (nothing else on, and I was curious about it). Apparently, Rick Springfield was one of the people who auditioned for the lead male role (that went to Maxwell Caufield in OTL). Springfield was big at the time (Soap and Pop star), so maybe he makes the movie do better, and they go on to have at least one more sequel (the original plan was to make four movies and then have a TV series).
Rock N' Roll High School (https://www.imdb.com/title/tt0079813/?ref_=rvi_tt):
Director Allan Arkush tried to get the film produced for several years, and he had some different ideas. One of the ideas: High School Spirit of 76. If that got made, I wonder if that would have been similar to Dazed and Confused.
