Jane Hamsher (born Jane Murphy; July 25, 1959) is a US film producer, author, and blogger best known as the author of Killer Instinct, a memoir about co-producing the 1994 movie Natural Born Killers with Don Murphy (no relation) and others,[9] and as the founder and publisher of the politically progressive blog FireDogLake (2004 – 2015).

[7] A few months later she raised money for a similar rental in Washington, D.C., called "Plame House", which served as a base for covering the Scooter Libby trial.

"[26] The film starred Woody Harrelson, Juliette Lewis, Tom Sizemore, Rodney Dangerfield, Robert Downey, Jr., and Tommy Lee Jones.

It was co-produced with Thom Mount and Arnon Milchan, and its credited screenwriters included Stone, Dave Veloz, and Richard Rutowski.

[27] Subsequently, Hamsher and Murphy also co-produced two 1998 films, including Brandon Boyce's screen adaptation Apt Pupil, from the Stephen King novella, directed by Bryan Singer and starring Ian McKellen, Brad Renfro, and David Schwimmer, and Permanent Midnight, adapted by Jerry Stahl and David Veloz from Stahl's autobiographical novel and starring Ben Stiller, Maria Bello, and Elizabeth Hurley; and the 2001 thriller From Hell, based on Terry Hayes and Rafael Yglesias' adaptation of the graphic novel From Hell, by Alan Moore and Eddie Campbell, directed by the Hughes Brothers, and starring Johnny Depp, Heather Graham, Ian Holm, Robbie Coltrane, Ian Richardson, and Jason Flemyng.

"[28] As Entertainment Weekly put it, "Stone is painted as a hard-partying womanizer who pits his underlings against each other and plays mind games....Tarantino gets off less easily.

[28] On his website, Murphy says that when Tarantino's former manager, Cathryn Jaymes, "came back with her notes [on the manuscript] my then partner lost it on her, I guess because she didn't want to make changes.

"[31][32] Jane Hamsher is listed as leading the CommonSense Media Advertising Network,[33] which includes Eschaton, FireDogLake, FiveThirtyEight, and Think Progress.

[39] Among other blogger conference programs, she participated in the South by Southwest (SXSW) Interactive Panels, held in Austin, Texas, from March 9 to 13, 2007, in which she also moderated Dan Rather's "Keynote Interview" event on Monday, March 12,[40] and in the panel on "Political Blogging: Macaca Mania" at the BlogWorld & New Media Expo 2008, in Las Vegas, Nevada, on September 20, 2008.
