The 59-year-old media mogul stars in director Lee Daniels's latest film

Oprah‘s back – on the big screen, that is – in The Butler.

Based on the life of Eugene Allen, the White House head butler who served eight presidents during a 34-year career, the film stars Forest Whitaker playing a character called Cecil Gaines. Oprah plays his wife, Gloria Gaines.

As shown in the intriguing two-minute, thirty-second trailer, the OWN network mogul, 59, shows off the acting chops that once earned her an Oscar nomination, for 1985’s The Color Purple.

From delivering a dramatic slap to planting a kiss on Whitaker, Winfrey has landed a dynamic role – in her first film since Beloved, in 1998.

Directed by Lee Daniels, The Butler also stars Alan Rickman, Robin Williams, John Cusack, Jane Fonda, Cuba Gooding Jr., Alex Pettyfer, Minka Kelly, James Marsden, Terrence Howard, Lenny Kravitz, Melissa Leo, Vanessa Redgrave, Liev Shrieber and Mariah Carey. It’s set to open Oct. 18.
