- Crazy Awesome: Ossi Oswalda may have been pretty awesome in general, but she takes it to a new level as the eponymous Oyster Princess, whose preferred method of dealing with disputes seems to be to challenge and beat her opponents in a boxing match. There's a reason why this is considered the most iconic role of her career.
- Crosses the Line Twice: Ossi getting rid of her "training baby" by throwing it across the room! It would have been horrific had it happened to a real child, but the "baby" is clearly just being a doll — coupled with the instructor's extremely nonchalant reaction — makes the scene funny instead.
- Growing the Beard: Lubitsch himself felt that this was his "first comedy which showed something of a definite style." It was also the film which really made him a big name internationally.
- Hilarious in Hindsight: While drunk, Prince Nucki starts talking to a horse. Later the same year, Ernst Lubitsch and many of the same cast and crew would make The Doll, which actually features talking horses.
- Nightmare Fuel: Some of Ossi's expressions qualify. No, really.◊
- One-Scene Wonder: Kurt Bois as the very hammy Bandmaster, who only shows up for a few minutes to conduct said band.
- Retroactive Recognition: Gerhard Ritterband, who would later get a much larger role in The Doll, appears briefly as a mischievous kitchen boy.
- Scenery Porn: The palace looks gorgeous, and is very well shot.
- Signature Scene: The Foxtrot Epedemic.
- Values Dissonance: While arguably part of the satire, Mr. Quacker — a wealthy, white American — having a quartet of black manservants doing his every bidding does, at the very least, date the film to a time before the Civil Rights Movement. It is eventually shown that most of Quacker's servants aren't black, but that just makes it more noticeable how all of his personal assistants are.
YMMV / The Oyster Princess
