Clive Owen and Nicole Kidman Sizzle in ‘Hemingway & Gellhorn’ Trailer

Celebrated war correspondent Martha Gellhorn was on the front lines of virtually every significant international conflict for 60 years. And while her work was highly respected, it was her brief and tumultuous marriage to author Ernest Hemingway that takes center-stage in 'Hemingway & Gellhorn,' an upcoming HBO film with Clive Owen and Nicole Kidman in the title roles.

The pair met in Florida in 1936 -- Gellman initially described Hemingway as a "large dirty man in disgustingly soiled clothes" -- and covered the Spanish Civil War in tandem, living together off and on for four years before marrying in 1940. Still, Gellhorn resented the fame she got as Hemingway's third wife, once saying that she had no intention of "being a footnote in someone else's life."

Her fierce independence seems to be the backbone of 'Hemingway & Gellhorn.' And if the trailer below is any indication, the chemistry between Kidman and Owen is palpable and could help make the saga a serious contender during awards season next year.

'Hemingway & Gellhorn' premieres May 28 on HBO.
