You have to be a real comic book head to know that Thor actually had a human secret identity for decades named Donald Blake. In the original Thor comics, Blake would tap his enchanted cane on the ground and transform into the God of Thunder.
In recent years, Blake has been basically erased from the comics in order to make Thor his own, solo character. But Thor director Kenneth Branagh gave fans of the books a subtle wink when Jane Foster (Natalie Portman) gave Thor (Chris Hemsworth) the clothes of her ex-boyfriend, named Dr. Donald Blake. He would later use this name while in S.H.I.E.L.D. custody to protect his identity.
