An audition rejection usually means grabbing your coat, thanking everyone in the room, and trying not to think about it on the ride home. Occasionally, though, casting directors reject the role and keep the actor. Someone walks in hoping to play the hero and leaves as the villain, reads for one sitcom weirdo and becomes another, or impresses producers enough that they create an entirely new character. A few of these swaps now feel almost impossible to imagine any other way, which probably says something nice about casting directors actually knowing what they are doing. Here are 15 actors who auditioned for one role and wound up playing somebody completely different.IMDbTom Hiddleston Wanted to Be ThorTom Hiddleston originally auditioned to play Thor, even putting on muscle for the part, before Marvel decided his particular talents made considerably more sense for Loki.IMDbCillian Murphy Put on the Batman SuitCillian Murphy actually screen-tested as Bruce Wayne in the Batman suit, but Christopher Nolan liked him enough to redirect him toward Jonathan Crane, better known as Scarecrow.IMDbTom Felton Tried Harry and Ron FirstBefore becoming Draco Malfoy, Tom Felton was tested for both Harry Potter and Ron Weasley, complete with different hair colors, before casting landed him in Slytherin instead.IMDbRainn Wilson Took a Shot at Michael ScottRainn Wilson auditioned for both Michael Scott and Dwight Schrute on his first day, later admitting his Michael was basically a bad Ricky Gervais impression.
