Duffy could follow in the footsteps of fellow Welsh singers Tom Jones and Dame Shirley Bassey by recording the next James Bond theme.
Work has already started on the follow-up to 'Quantum of Solace' - starring Daniel Craig as the British spy - and one of the film's producers wants the Welsh singer to record the title song.
Producer Michael G. Wilson told Britain's The Sun newspaper: "I would love to get Duffy to sing the next tune. I think she is wonderful. Amy Winehouse would be good too.
"We have started work on the new film, which I can't say anything about. Daniel Craig is very keen to get going."
'Back to Black' singer Amy Winehouse was due to submit a track for 'Quantum of Solace' with producer Mark Ronson, but sessions were stopped as she reportedly "wasn't ready" to record.
Duffy - whose song 'Mercy' picked up the PRS Most Performed Work prize at the Ivor Novello Awards yesterday (21.05.09) - has revealed she is to make her film debut, although admits she isn't too enthusiastic about it.
She reportedly said: "I'm making a movie. It'll probably be rubbish."
