* NonSingingVoice: Robin Ward sang "The Sweetheart Tree" instead of Natalie Wood. Wood sang "My Country 'tis of Thee" herself earlier on...you can tell because she sounds off-key.
* ProductionPosse: Creator/BlakeEdwards, director and co-writer, apparently brought along a good number of the personnel he'd previously worked with on his [[Series/PeterGunn television]] [[Series/MrLucky shows]], most prominently Music/HenryMancini and Ross Martin.
* ThoseTwoActors: Tony Curtis and Natalie Wood in their third (and final) film together, and Tony Curtis and Jack Lemmon in their second of two. Although, ask anyone to name a Tony Curtis/Jack Lemmon film, they'll probably think of [[SomeLikeItHot the other one]].
