10 Movie Character Backstories Revealed Years Later
10. Alfred Met Thomas Wayne In The S.A.S. - The Dark Knight Trilogy
Michael Caine's rendition of Bruce Wayne's trusty servant Alfred Pennyworth made his debut in 2005's Batman Begins, but it wasn't until Caine was doing the press rounds for The Dark Knight Rises in 2012 that he revealed the character's unspoken backstory.
Caine confirmed that he came up with his own origin story for Alfred which was compelling enough to receive the blessing of director Christopher Nolan himself.
The backstory explains that Bruce's (Christian Bale) father Thomas Wayne (Linus Roache) visited the S.A.S. base in Herefordshire to see a friend, and in the mess hall he encountered a badly wounded Sergeant, who was none other than Alfred.
Rather than go back to fight, Alfred was appointed to oversee the Sergeant's mess, which involved serving food and drinks, in turn preparing Alfred for his eventual job working for Thomas at Wayne Manor.
It's a perfect example of a backstory that so perfectly fits the context of the character and the world they're established within. Though it doesn't have much of an impact on the overarching story at all, it's a neat sliver of background character building.
