Hemsworth, 33, who will reprise his role as the Marvel superhero in "Thor: Ragnarok", was inspired after he surprised ailing youngsters at the Lady Cilento Children's Hospital in Brisbane, Australia, reported Female First.
Alongside a picture of himself and his co-star Hiddleston, who plays Loki in the forthcoming film, he wrote, "Met the real superheroes of the world at @ladycilentochildrenshospital. A huge shout out to all the brave kids who are an inspiration to all of us! @twhiddleston #madepossiblebychf #ladycilentochildrenshospital #juicedtv (sic)."
Alongside a picture of himself and Chris with two patients with massive smiles on their faces, he wrote, "Whosoever holds this hammer, if he be worthy, shall possess the power of Thor!" (i.E. Everyone but the weirdo in the black suit). Unforgettable meeting all the children @ladycilentochildrenshospital. They're the real heroes. #madepossiblebychf #juicedtv #ladycilentochildrenshospital (sic).
