* AwardSnub: Missing out on Oscar nominations for his work in ''Film/{{Fargo}}'' and ''ComicBook/GhostWorld''.
* SugarWiki/HeReallyCanAct: People familiar with him mainly as a homicidal transvestite in ''Film/BillyMadison'' will be surprised at his acting chops in ''Series/BoardwalkEmpire''.
** And even before that on ''Series/TheSopranos'' and work in Creator/TheCoenBrothers films.
* SugarWiki/HeartwarmingMoments: Returning to his old firehouse to help rescue people on 9/11 definitely counts. As well as being stabbed to protect a friend in a fight.
* MemeticMutation: This [[http://chickswithstevebuscemeyes.tumblr.com/ site]]. Also dovetails into NightmareFuel. And then there's [[http://ultraimg.com/images/b91c5ec0-3dfe-0133-8e81-0e17bac22e39.gif this]].
* MoneyDearBoy: If a job pays well enough, he'll generally do it.
* RealLife/MeanCharacterNiceActor: Despite playing immoral/amoral weasels, he has been described as a consummate professional whom everyone likes. A former fire-fighter, he immediately went to his old firehouse and helped look for survivors of the 9/11 attacks.
* OneSceneWonder: Usually any time he's in an Creator/AdamSandler film.
* PlayingAgainstType:
** ''Series/BoardwalkEmpire'', as noted above. Enoch Thompson is a powerful, charming [[TheDon Don]], leading a successful career as a charismatic politician and powerbroker, a commanding gangster, and all-around king of Atlantic City.
** Donny in ''Film/TheBigLebowski'', a nice, upbeat, naive guy who's never allowed to speak for more than a second. The last part was done as a nod to the fact the his character in ''Film/{{Fargo}}'' wouldn't shut up.
** An earlier example is ''InTheSoup'' in which his character is a struggling but Sweet Film Director with an unrequited crush on Jennifer Beals' character
** His character in the ''Series/TalesFromTheCrypt'' episode "Forever Ambergris" is a nice (if naive) fellow. Among other things, he's, a gifted photographer who either doesn't notice how gifted he is or just doesn't let it go to his head.
** In the German biopic ''John Rabe'', he plays a heroic American doctor.
* WhatCouldHaveBeen:
** Buscemi was considered to be cast for the role of [[Franchise/{{Batman}} The Scarecrow]] in the cancelled Franchise/{{Batman}} film, ''Batman Triumphant''.
** If Creator/JohnMalkovich hadn't been up for it, the film might have been called ''[[Film/BeingJohnMalkovich Being Steve Buscemi]]'' instead.
