Actor Allusion: Paul's "decorator" says to him, "Well, love has found Andy Hardy." Andy Hardy was the lead character of a series of films (including Love Finds Andy Hardy) portrayed by Mickey Rooney, who plays Mr. Yunioshi.
Audrey herself is a Fake American, though her foreign accent is explained as a result of speech lessons. In the movie the accent is so she can casually pass herself off as a Fake Brit, to make her more marketable as an aspiring actress.
Mickey Rooney's unfortunate turn as Holly's Japanese neighbor.
Old Shame: Both Richard Shepherd and Blake Edwards had regretted of casting Mickey Rooney in Yellow Face. Mickey Rooney himself stated if he'd known that so many people would be offended, he would never have taken the role, but otherwise doesn't regret his performance itself, saying they had much fun during the shooting and everyone at Hollywood (including Asians!) had congratulated him upon the release of the movie, with the criticizing only coming much later.

The film also gave its name to a One-Hit Wonder90s song by Deep Blue Something where the song's protagonist, who is on the verge of breaking up with his girlfriend, uses the film as a common ground to maintain their relationship.
