Tom Hiddleston has revealed that Thor 2 will be "amazing".
The British actor is reprising his villainous role as Loki alongside returning cast members Chris Hemsworth and Natalie Portman in the highly anticipated sequel titled Thor: The Dark World.
"It's fantastic, truly. We are making an amazing film, and we're having a wonderful time," he teased.
"It's so exciting to have established characters and an established setting in the world, and we are working so hard to cook up something new."
Tom - who is helping to judge the Jameson Empire Done In 60 Seconds short film competition - said that the second film will show a different side to the characters.
"That is what is exciting me - taking what we know, taking what we love and deepening it and giving it an extra dimension. I think director Alan Taylor is really shaping up the world of Asgard and the world of these characters," he added.
Thor: The Dark World is expected for release in November 2013.
