Losers (1967) featuring Tom Laughlin as Billy Jack. Bleaker in tone are such films as Hi, Mom! (1970) in which vet Robert De Niro films pornographic home movies before deciding to become an urban guerrilla, The Strangers in 7A where a team of former paratroopers blow up a bank and threaten to blow up a residential apartment building, The Hard Ride (1971) and Welcome Home, Soldier Boys (1972) in which returning vets are met with incomprehension and violence. In many films, like Gordon's War (1973) and Rolling Thunder (1977), the veteran uses his combat skills developed in Vietnam to wage war on evil-doers in America. This is also the theme of Taxi Driver (1976) in which Robert De Niro plays Vietnam veteran Travis Bickle who wages a one-man war against society whilst he makes plans to assassinate a presidential candidate. This film inspired John W. Hinckley to make a similar attempt against President Ronald Reagan. In a similar vein is First Blood (1982), which stars Sylvester Stallone in the iconic role of John Rambo, a Vietnam vet who comes into conflict with a small-town police department. Such films as Welcome Home, Johnny Bristol (1972), and The Ninth Configuration (1979) were innovative in depicting veterans suffering from post-traumatic stress disorder before this syndrome became widely known. In Born on the Fourth of July (1989) Tom Cruise portrays disenchanted Vietnam veteran Ron Kovic who, wounded in action and requiring the use of a wheelchair, leads rallies against the war. A more recent example is Bruce Dern's portrayal of a down-and-out veteran in the film Monster (2003). In television, the first Vietnam veteran to be a regular character in a U.S. dramatic series was Lincoln Case on Route 66. Case, played by Glenn Corbett, was introduced in 1963, long before the major U.S. buildup in Vietnam. "Linc" Case was initially portrayed as an angry, embittered man, not only because of his harrowing wartime experiences (which included being taken prisoner and escaping a POW camp) but also because of his grim childhood and continuing estrangement from much of his family. The show depicted his effort to make peace with himself and others. In the 1980s and 1990s, service in Vietnam was part of the backstory of many TV characters, particularly in police or detective roles. The wartime experiences of some of these characters, such as MacGyver, Rick Simon of Simon & Simon, or Sonny
