Rachel Weisz found learning the accordion “silly”.

The actress’ character in ‘The Brothers Bloom’ plays several musical
instruments, and although she had to take hours of lessons before shooting
started, she had the most difficulty with the bellowing squeezebox.
She explained: “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 wish 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.”
As well as becoming an amateur musician, Rachel also had to undertake magic
lessons, which was the toughest part of her preparation.
She added to Britain’s Daily Mail newspaper: “Most difficult were the card
tricks. I never knew how to shuffle a pack let alone do this amazing card
trick.
“I had to learn with someone from the Magic Circle. That was no fake,
believe me.”
However, one thing ‘The Mummy’ star didn’t do for herself was drive a luxury
sports car, as bosses didn’t trust her skills behind the wheel.
She said: “I wasn't allowed to be in the Lamborghini when it was in motion.
I was only allowed to be in it when it was still. They're what, a million
pounds?
“They didn't trust me behind the wheel. I'm actually a very good driver but
they didn't believe me.”
