Halle Berry is having doubts about playing Aretha Franklin in an upcoming biopic.

The Academy Award-winning actress - who the soul legend recently tipped to portray her on the big screen – insists she would be the wrong choice for the movie because of her lack of vocal talent.

She told E! News' Ryan Seacrest: "I can't sing! If I could carry a tune, I'd consider it. Someone should tell Aretha that I can't do her Justice."

Halle’s reluctance may not please the 68-year-old ‘Respect’ singer, who recently said she wanted the 44-year-old actress to portray her in the film based on her 1999 autobiography 'Aretha: From These Roots'.

She said recently: "Halle Berry is my pick for the older me and a younger actress has yet to be named."

The ‘Chain of Fools’ hitmaker – who is currently recovering from surgery for what is rumoured to be pancreatic cancer - also wants award-winning actors Denzel Washington and Terrence Howard on board the project.

Aretha admitted she has had many offers to make a film of her life but has been holding out for the right one.

She said recently: "For the last four years we've been talking about that and I've had a number of offers but unfortunately they were not good offers."
