All hail the God of Thunder! Just not, you know, that Marvel guy everybody knows about. No, we’re talking about Jon Mikl Thor, a.k.a. “Thor, The Legendary Rock Warrior.” Thor fronted the delightfully over-the-top metal group Thor in the ’70s and ’80s, then retired after the act failed to achieve the mainstream success of contemporaries like Kiss. Thor moved into film for a time, appearing in B-movies like Rock ’N’ Roll Nightmare, before eventually quitting entertainment altogether. But you can’t keep a hammer-wielding god down, and he eventually launched a comeback. Now, the world can know the full story: Deadline reports late fall 2015 will see the release of I Am Thor, a documentary about the metal rocker and his tumultuous life.
