Keira Knightley voices cancer charity's radio campaign

Actress Keira Knightley has urged her fans to use their spare time to raise money for a leading U.K. cancer charity.

The Pirates of the Caribbean star has recorded a new radio campaign for Marie Curie Cancer Care's Great Daffodil Appeal, urging the public to hit the streets to sell the organisation's trademark yellow flower emblem in March (13).

Knightley says, "We need volunteers to donate an hour of their time to help collect money for the Great Daffodil Appeal. The money you raise will help Marie Curie Cancer Care nurse terminally ill people in their final hours."

Actor Stephen Mangan has also voiced an advertisement for the charity, detailing his experiences of cancer.

He adds, "Marie Curie Nurses looked after my mother at home after she was diagnosed with terminal bowel cancer. A double blow followed when my father also died from a brain tumour; fortunately we were also able to care for him at home with Marie Curie Nurses at his side.

"When Marie Curie Nurses were caring for my mom, I used to sit by her bed and play the guitar, very badly I might add. We had many comedy moments at home with both mom and dad but that just wouldn't have been possible on a hospital ward.

"I'm from a large extended Irish family and my parents were very much the focal point, so having a Marie Curie Nurse there to look after them meant that we could be the family we are without having to worry about anything.

"I'm proud to be supporting the appeal and urging people to sign up to collect for the charity in March."
