Not far from the opening of X-Files: I Want to Believe, Gillian Anderson plans to star in and produce a biopic of Martha Gellhorn, a well-known journalist who trail blazed as a female war correspondent covering conflicts from the Spanish Civil War to Vietnam. She even lasted through strife in personal relationships that included a failed marriage to Ernest Hemingway.

Anderson’s company, Fiddlehead Productions acquired “Gellhorn: A Twentieth-Century Life,” a 2004 biography by Caroline Moorehead.

Anderson, who opens July 25 in The X-Files: I Want to Believe, plays Gellhorn.
