Natalie Portman would love to live and work in the same place.

The jet-setting Thor: The Dark World star is "envious" of her British co-stars who are able to live and work in the same city because more and more Hollywood productions are making use of London's production studios: "I love working here in London and I'm envious of British actors and British crews because American actors, we end up like gypsies - movie to movie, moving cities every time. But you can have such a fulfilling, wonderful, rich career here between the theatre, the TV, and the film all in one place. It's pretty cool to get to live and work in the same place."

The 32-year-old beauty - who has two-year-old son Aleph with her husband Benjamin Millepied - also said her mother Shelley Hershlag, who is her agent, often lends out family photos of her as a child to decorate the sets of her films, but joked her mum keeps using the same ones. "I guess the funny thing is that it is the same set of photos she always lends out for every movie I've done for the past 20 years. There's a lot of characters that shouldn't have the same experiences and family photos, but do. Also, all sorts of people have been Photoshopped into them - there's some interesting ones of me and Tobey Maguire from when I'm young, but not real, of course," she explained.
