HBO to develop Katherine Graham biopic

Washington Post publisher oversaw Watergate

HBO Films is developing a biopic about Katharine Graham, the late publisher of the Washington Post who oversaw the paper's Watergate coverage leading to the resignation of President Richard Nixon.

The untitled project, which is in the very early stages of development, is being written by Joan Didion and will follow Graham's ascendancy to the top post at the newspaper.

Should the project go forward, HBO Films is planning to offer Laura Linney the role of Graham, who took over the Post after her husband, Philip, committed suicide in 1963. Graham -- who won a Pulitzer Prize for her memoir, "Personal History," in 1998 -- died in 2001.

Laura Ziskin, Pam Williams and Julie Goldstein are executive producers. Robert Benton is attached to direct.
