For most of the television and film history of Batman, Alfred has always been portrayed as the loyal butler who tends to Wayne Manor and most of Batman’s gadgets. He’s had some background here and there, notably in Christopher Nolan’s Dark Knight films, but usually he is a passive character that acts as the emotional anchor for Bruce Wayne away from his life as Batman.
Not so much according to some newly released / leaked Batman V Superman tie-ins. It would seem that Jeremy Irons’ version of the DC Comics mainstay will be taking on a bit more of a hard edge with an active role in Batman’s war against crime. According to Cinema Blend, Wayne Manor is in disrepair because Alfred is not a butler. He’s a tactical bad-ass with a firm background in the SAS, experience fixing and managing most of Batman’s gadgets, and apparently has a hand in training Bruce Wayne for his time as Batman.
