* FakeNationality: His most iconic part in ''Film/DieHard'', he used it on a guest spot in ''WesternAnimation/KingOfTheHill''.
* 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 [[MagnificentBastard Hans]] [[Film/DieHard Gruber]], [[Film/RobinHoodPrinceOfThieves The Sheriff of Nottingham]], [[JerkWithAHeartOfGold Alexander]] [[Film/GalaxyQuest Dane]], [[{{Jerkass}} Severus]] [[Film/HarryPotter Snape]], and Rasputin, who is... ''Rasputin''. Off-screen, Rickman was a low-key, modest man who stayed out of the limelight, avoided the paparazzi, and when it came to his fans, was a giant freaking teddy bear, quick with the jokes and hugs.
* 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.
