Busy actress Keira Knightley, who hardly gets much down time while shooting, usually relaxes between takes with a book, but can't focus on anything too heavy.
"On a film like this there isn't a lot of waiting. We had 24 days, so it was just like go, go, go,” the 29-year-old said on the set of her latest movie “Begin Again”.
"Normally what do I do? I have a cup of tea and I like book tapes or really trashy novels, because you can't read something difficult when you're working on something else."
Knightley co-stars with Maroon 5 singer Adam Levine, currently developing his film career, and though it was his first film, she thought he was a very good actor, reports femalefirst.co.uk.
She said: "I'd actually seen him live and that energy makes an experience. He's a born entertainer, so I wasn't worried about him expressing himself. He didn't need any tips. He's a natural actor and a very lovely man to work with, so it was a lot of fun."
She had to sing in the movie and admits she didn't particularly enjoy the performance scenes.
She told Britain's OK! magazine: "I'm not a singer or a musician so no, I didn't enjoy it. I had to fake it.
"It was fun, but I think I'm bad at (singing)."
