Chris Hemsworth is the best actor to work with: Natalie Portman

London: Actress Natalie Portman feels Chris Hemsworth has great on-screen chemistry with ever co-stars of him. The 32-year-old actress, who is sharing the screen space with the Australian heartthrob in the action film “Thor: The Dark World”, said he is one of the best actors in Hollywood, reported Contactmusic.

He’s the nicest, most professional, best actor. He’s very easy to be around. It’s definitely not something we needed to work at and I think that says so much about him. He’s a great guy,” she said during the world premiere of the new action movie at the Odeon in London’s Leicester Square last night. Hemsworth, 30, can not quite believe he has so many fans, as he was almost rendered speechless by the warm reception he received at the screening. “I love shooting in London. I’ve done a number of films here now and to be back with this film that we started three years ago to this kind of reception is a dream come true,” he said. `The duo were joined at the red carpet event by Tom Hiddleston, Idris Elba, Christopher Eccleston, Kat Dennings, Stellan Skarsgard, director Alan Taylor, and ‘The Avengers’ director Joss Whedon.
