Thor: Ragnarok star Chris Hemsworth has shared a new photo of himself and director Taika Waititi wearing perhaps the greatest t-shirts of all time. His artwork takes the title of Thor: Ragnarok and turns it into Thor: Ragna-ROCK with Marvel?s god of thunder shredding a guitar and gladiatorial Hulk manning the drums. Thor: Ragnarok is inspired by the classic The Mighty Thor comics of Walt Simonson and the Incredible Hulk storyline "Planet Hulk" by Greg Pak, Carlo Pagulayan and Aaron Lopresti.
