Cabaret/YMMV

Adaptation Displacement: The movie and musical are much more well-known than the play "I Am A Camera" and the original stories by Christopher Isherwood.
Alternative Character Interpretation: The Emcee is especially prone to this, given his ambiguous nature as relates to the actual story.
Funny Aneurysm Moment: Natasha Richardson played Sally in the recent revival... and her singing "From cradle to tomb isn't that long a stay!" has become a lot harsher given she died suddenly and tragically a few years later.
Misaimed Fandom: "Tomorrow Belongs to Me" is popular among neo-Nazis, who are either oblivious to or don't care about its origins, and several racist or neo-Nazi bands have covered it.
Tear Jerker: "I Don't Care Much".
