Weisz learned four instruments for role

Rachel Weisz had to learn to play four musical instruments for her part in The Brothers Bloom.

The actress not only had to get to grips with the accordion, banjo, guitar and fiddle, but she also had to overcome a language barrier with her teacher.

She told the Daily Mail: "We were in Serbia when we were doing the scenes and I learned the accordion with a professor who spoke no English and I spoke no Serbian.

"I just wished someone had made a documentary of me trying to learn the accordion because it was so silly.

"Then I had to learn the banjo, guitar and fiddle. I was doing my homework in my room for hours learning the chords. I had to look as if I knew how to play these instruments."

The 38-year-old recently revealed that producers banned her from driving a Lamborghini on the film's set in case she damaged it.
