Hollywood producer Larry A. Thompson’s “Liz & Dick” debuts Sunday on Lifetime, but Thompson already has his next biopic in the works.

The subject? Oprah.

“I’ve optioned Kitty Kelley’s book on Oprah Winfrey,” said Thompson, who said his four-hour miniseries on the Queen of Talk is in development.

Who would he like to cast as Oprah? Viola Davis.

Lindsay Lohan plays Elizabeth Taylor in “Liz & Dick,” about the actress’ tempestuous relationship with Richard Burton.
