Dionne Warwick has spoken out against the upcoming Whitney Houston biopic I Wanna Dance With Somebody.

“I want them to let Whitney rest in peace,” she told The Los Angeles Times. “Leave her alone. Ten years [since she died]–it’s time to let her sleep.”

Clive Davis, who is executive producing the film, has said the film will be an unvarnished look at Houston's life.

“I have a mission here,” he previously said to Variety. “I have a mission to make sure that for all time that the full picture of Whitney Houston is captured in a no-holds-barred film that is musically rich and shows her genius and more of her character than we have seen to date.”

'I Wanna Dance With Somebody' will be directed by Kasi Lemmons and will star Naomi Ackie as Houston and Ashton Sanders as Bobby Brown.

Moses Ingram will also play Robyn Crawford, Houston’s former creative director, assistant and best friend. She has also written a book, A Song For You: My Life With Whitney Houston, which details their friendship and romantic love.

Houston’s sister-in-law Pat Houston will produce the film for the Houston Estate, meaning that Houston’s catalog of music will be featured. Other producers include Primary Wave Music’s Larry Mestel and Denis O’Sullivan.
