* BigBudgetBeefUp: While crafted as a loving tribute to the often-dirt cheap medium of silent film, the sheer scale, ambition, and length of Edwards' story made the film, at the time, the most expensive comedy in history (roughly $90 million when adjusted for inflation).[[note]]Part of this was due to contractual negotiations; after Curtis's agent got him signed for $25,000 more than Lemmon and Wood, he proceeded to then advocate for them to all be paid equally.[[/note]]
* DuelingWorks: The far more commercially and critically successful ''Film/ThoseMagnificentMenInTheirFlyingMachines'' had been released not a month prior by Fox, which hurt the film in both departments (though it still made over double its budget at the box office).
* NonSingingVoice: Robin Ward sang "The Sweetheart Tree" instead of Creator/NatalieWood. 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: Creator/TonyCurtis and Creator/NatalieWood in their third (and final) film together, and Curtis and Creator/JackLemmon in their second of two. Although, ask anyone to name a Tony Curtis/Jack Lemmon film, they'll probably think of [[Film/SomeLikeItHot the other one]].
* WhatCouldHaveBeen: Creator/CharltonHeston was originally offered the role of The Great Leslie. He considered it a "funny script" but had to turn the part down when the production schedule for ''The Agony and the Ecstasy'' (1965) was delayed.
