And he’s now taken to Twitter to sing the praises of the latest, stating that Taika Waititi and Marvel have created a “modern masterpiece” with Thor: Ragnarok.

In Marvel Studios’ “Thor: Ragnarok,” Thor is imprisoned on the other side of the universe without his mighty hammer and finds himself in a race against time to get back to Asgard to stop Ragnarok—the destruction of his homeworld and the end of Asgardian civilization—at the hands of an all-powerful threat, the ruthless Hela. But first he must survive a deadly gladiatorial contest that pits him against his former ally and fellow Avenger—the Incredible Hulk.
