If we think of the narrative arc of the Thor films, with his Avengers appearances sprinkled in, it becomes clear that they form something of an origin story for an Asgardian King. He has always been destined to take the throne in the absence of his father, Odin – but Thor has thus far been reluctant, and avoided it at all costs. This has caused problems for Asgard – most notably when last we saw the throne, and it had Loki sitting in it, impersonating Odin. Thor: Ragnarok, being the third instalment, will apparently bring that arc to a satisfying conclusion – as a new promotional clip sees the God Of Thunder finally take his rightful seat.
