Michael Caine reveals the secret history of Batman's Alfred

Michael Caine reveals the secret history of Batman's Alfred 
Christopher Nolan accomplished many things between Batman Begins and The Dark Knight Rises, but one thing that was never fully realized was the backstory of Bruce Wayne's butler, Alfred Pennyworth. Good thing actor Michael Caine came up with one himself.

Nolan provided some small tidbits as to who Alfred was, most notably that he was ex-special forces, but beyond that, we just don't know. Thankfully, Caine comes to the rescue. The important stuff begins around 1:05.
What's interesting here is that, since Nolan was, apparently, so trusting of his actors, that may very well be the official backstory for this version of Alfred.
What do you think? Is that story enough satisfy the Bat-fan in you? VIDEO
