Chris Hemsworth has real clout as the hot-tempered thunder god in this pleasing fantasy.

In the realm of Asgard, Thor’s stirring up trouble with age-old enemies, the Frost Giants, which ends with his stern father, Anthony Hopkins’ one-eyed ruler of the gods, Odin, banishing him to Earth.

Landing with a thump in New Mexico, Thor’s discovered by Natalie Portman’s storm-chasing scientist and there’s some cheeky fish-out-of-water comedy as he comes to terms with his new surroundings and mortal form.

The men in suits from spy agency SHIELD are not amused, but Thor is more than a match for them, but, back in Asgard, he has a far more formidable foe in the shape of his troublesome brother, Loki (Tom Hiddleston).

Director Kenneth Branagh’s fantasy has plenty of style and comic-book fans will lap up the muscular heroics, bruising battles and cameos by other members of the Marvel Comics universe.
