I need to get off this planet. Crown Prince of Asgard Thor (Chris Hemsworth) is imprisoned on the planet Sakaar and he has a race against time on his hands to return to Asgard and stop the destruction of the world (Ragnarok) by the evil goddess of death, Hela (Cate Blanchett) – who turns out to be his sister. It means teaming up with his awful brother Loki (Tom Hiddleston) who is alive after all but can he be trusted? Dad Odin (Anthony Hopkins) is on hand to guide him … Written by Eric Pearson and Craig Kyle & Christopher Yost, director Taika Waititi responds to the humour in the material and the cast are given their funniest outing yet, with a great joke cameo at the beginning. Jeff Goldblum turns up as a Grandmaster glorying in gladiatorial contests and Bruce Banner aka The Hulk (Mark Ruffalo) arrives to join The Revengers – as they call themselves – to help them take on their vicious sister. Valkyrie (Tessa Thompson) joins in on this mission as a whole society is at stake with Heimdall (Idris Elba) trying to lead them to safety. There’s a lot of intentionally odd 80s-style effects, self-deprecating humour (Thor’s masculinity is tested with a haircut) and a lot of nicely set up action sequences. Good-natured comic book fun in the second Thor sequel and the seventeenth episode of the Marvel series.
