* FakeNationality: His most iconic part in ''Film/DieHard'', he used it on a guest spot in ''WesternAnimation/KingOfTheHill''.
** The ''King of the Hill'' example is a pretty [[MindScrew roundabout example]], since he's a British actor [[FakeAmerican playing an American]] who himself is playing a FakeBrit.
* IAmNotSpock: Most people who are too young to remember ''Film/DieHard'' will instantly associate Alan Rickman with [[Film/HarryPotter Severus Snape.]]
* RealLife/MeanCharacterNiceActor: Look through his filmography on Website/{{IMDb}}. It includes major {{Jerkass}}es such as [[Film/DieHard Hans Gruber]], [[Film/RobinHoodPrinceOfThieves The Sheriff of Nottingham]], [[Film/GalaxyQuest Alexander Dane]], [[Film/HarryPotter Severus Snape]], and Rasputin, who was, well, ''[[UsefulNotes/RasputinTheMadMonk Rasputin]]''. Off-screen, Rickman was a low-key modest man who stayed out of the limelight, avoided the paparazzi, and was a giant teddy bear and quick with the jokes and hugs when it came to his fans.
* SecretKeeper: Creator/JKRowling told Alan Rickman Severus Snape's entire backstory - particularly, the content discussed in ''Literature/HarryPotterAndTheDeathlyHallows'' - as she felt it was crucial to his portrayal of the character in the films. He kept the fact that he had this knowledge secret from everyone until she revealed this herself, and even then, never revealed exactly what she'd said. Respecting his wishes, Rowling didn't tell anyone either until after his death.

-->'''@sarahrosefrank:''' Will you tell us the piece of information that you told Alan Rickman about Severus Snape? Or will that forever be a secret? :-)
-->'''Creator/JKRowling:''' I told Alan what lies behind the word "always".
* ThoseTwoActors: With Creator/EmmaThompson. They played two of the main characters in the 1995 film version of ''Literature/SenseAndSensibility'', an FBI/detective duo in ''Judas Kiss'', Hogwarts professors in ''Film/HarryPotter'', a married couple in ''Film/LoveActually'', and ex-lovers in ''The Song of Lunch''.
* WhatCouldHaveBeen:
** He auditioned for the part of Moff Jerjerrod in ''Film/ReturnOfTheJedi''.
** He turned down the role of Alec Trevelyan in ''Film/GoldenEye''. The character was originally written as a mentor to Film/JamesBond.
