First Blood (also known as Rambo or Rambo: First Blood outside the United States), is a 1982 action/thriller film directed by Ted Kotcheff. The film stars Sylvester Stallone as John Rambo, a troubled and misunderstood Vietnam War veteran, with Sheriff Will Teasle (Brian Dennehy) as his nemesis and Colonel Samuel Trautman (Richard Crenna) as his former commander and only ally. It was released on October 22, 1982. Based on David Morrell’s 1972 novel of the same name, it was the first of the Rambo series. Unlike the sequels which were war adventure films set in foreign countries, First Blood was a post-Vietnam War psychological thriller set in the United States. The film was chosen by Empire magazine as one of The 500 Greatest Movies of All Time.
In lower Washington State in December 1981, John Rambo, a Medal of Honor-winning former Green Beret, finds that he is the last surviving member of his unit. Disconsolate after finding out the death of his last remaining comrade, he wanders into the nearby town of Hope, WA, where local sheriff Wilfred Teasle gives him a lift – straight out of town; Teasle explains in no uncertain terms that “drifters” like Rambo are not welcome in town. Insulted by Teasle’s action, Rambo boldly returns to town and is falsely arrested for vagrancy and resisting arrest. His treatment at the hands of Teasle’s deputies grows even harsher, as he is beaten and sprayed with a firehose. When the deputies try to force-shave him, Rambo (briefly flashing back to memories of Communist torture in a prison camp) goes berserk and breaks free; he commandeers a motorcycle and flees into the nearby hills.
As the sheriff’s posse purses, one belligerent deputy violates orders and tries to kill Rambo – and in the process an accident leaves the deputy dead. Misunderstandings pile up and Teasle shoots Rambo, but Rambo survives and when the posse press their pursuit, Rambo uses his well-honed survival and combat skills to cripple the posse and leave Teasle with a warning to leave him alone – a warning repeated by Rambo’s recently arrived former commander, who understands how outclassed Teasle and newly arrived National Guardsmen are against Rambo in the thick forest. Teasle, however, wants Rambo dead, and the pursuit leads to a bloody confrontation and a final plea for and end to the violence.
