You may or may not have heard, but Marvel have took the shocking approach of replacing Thor in comics with a now female version. I know it is far to early to even speculate on a female Thor replacing Chris Hemsworths Thor in the Marvel Cinematic Universe. While it may be early, that's not to say that it would not be fun as heck to speculate.
Marvel Editor-In-Chief Alex Alonso did say in the interview regarding the change of gender "This really is the one Thor for an extended period of time for which we have no real exit plan" with Time. So it is easily within the realm of possibility that Chris could be replaced in the future, rumour has it he has three movies left on his contract one being "Avenger: Age Of Ultron" and obviously "Thor 3" could his third remaining movie be the end of Hemsworths Thor? As we said it's in the realm of possibilities. Here are five actresses I think could take over live action Thor if the opportunity arose for them, the order they are down in are not in a best to worst or anything. They're just the five I chose.
