“Empire” may be the biggest network drama in years, but co-creator Lee Daniels isn’t satisfied quite yet. In an interview with The Hollywood Reporter, the director admitted to putting in multiple requests to Oprah Winfrey to guest star on the show. As of yet, Winfrey hasn’t agreed, but Daniels, who directed the star in the 2013 film “The Butler,” is optimistic.

“I tell him: ‘Lee, it’s not enough that you’ve taken every viewer possible on Wednesday night,” Winfrey said. “Now you want me to leave my own network?'”

“I’m wearing her down!” Daniels said in response.

“Empire” became a quick smash hit after its debut this past January on Fox. The show has continued to grow its audience and top network drama ratings each week.
