Noomi Rapace doesn't "need to be polite" when she works with Tom Hardy.

The Swedish actress appears alongside the Batman: The Dark Knight Rises star in Soviet-era thriller Child 44, and says their on screen chemistry comes from being such good friends off-camera:

"I met Tom two years previously and we were looking for something to work on. What was really great was that we know each other really well, and we really trust each other, so we don't need to be polite, we don't need to start from zero. We could just melt into the next one. We had so much for free. It felt like we were this gypsy family coming from New York with all our family and the next stop was Prague [in The Czech Republic]."

Noomi also told how one of the main reasons she wanted to become an actress and travel the world was so it got her away from the cold winters of her native Sweden, but also acknowledged they were always a good time for her creatively. "Because it's dark and cold out, it forces people to be creative, you can't just sit and hang out. For six months it's dark and lonely and forces some creativity," she added.
