Mark Lane (born February 24, 1927, The Bronx, New York, USA – died May 10, 2016, Charlottesville, Virginia, USA) was an American attorney and former New York state legislator, civil rights activist, and Vietnam war-crimes investigator. He wrote many books. Including "Rush to Judgment" and "A Citizen's Dissent", two major books published in the immediate wake of the John F. Kennedy assassination that questioned the conclusions of the Warren Commission. Another book "Plausible Denial" published in 1991, continued his interest in the JFK assassination. Lane was thought to be a screenwriter for the 1973 action movie, "Executive Action" starring Burt Lancaster and Robert Ryan, but in actuality he only worked on the first draft of the screenplay. He collaborated with Donald Freed on it and after seeing subsequent drafts, they complained both privately to the producer and publicly at press conferences, pointing out errors in the work.
