Idris Elba has admitted that reprising his role as Heimdall in Thor 2 was "torture" because his costume didn't fit.
The Luther star returns to play the Asgardian gatekeeper in the Thor sequel, The Dark World, alongside Chris Hemsworth and Tom Hiddleston.
"It was torture actually. The costume really doesn't fit me any more," he said.
"But it was good fun, it was good to bring it back. We got to experiment a little bit and expand into the character and the world more."
"I like Alan a lot. He knows what he wants, he's a really technical wizard and knows how to make a good film," he added.
Thor: The Dark World opens in cinemas on October 30.
