Dennis Lee Hopper (May 17, 1936 – May 29, 2010) was an American actor, filmmaker, and visual artist. He attended the Actors Studio, made his first television appearance in 1954, and soon after appeared in Giant (1956). He was on The Rifleman (season 1 episode 1), as Vernon Tippert. In the next ten years he made a name in television, and by the end of the 1960s had appeared in several films, notably Cool Hand Luke (1967) and Hang 'Em High (1968). Hopper also began a prolific and acclaimed photography career in the 1960s.
Hopper made his directorial film debut with Easy Rider (1969), which he and co-star Peter Fonda wrote with Terry Southern. The film earned Hopper a Cannes Film Festival Award for "Best First Work" and a nomination for the Academy Award for Best Original Screenplay (shared with Fonda and Southern). Journalist Ann Hornaday wrote: "With its portrait of counterculture heroes raising their middle fingers to the uptight middle-class hypocrisies, Easy Rider became the cinematic symbol of the 1960s, a celluloid anthem to freedom, macho bravado and anti-establishment rebellion". Film critic Matthew Hays wrote "no other persona better signifies the lost idealism of the 1960s than that of Dennis Hopper".
Following the critical and commercial failure of his second film as director, The Last Movie (1971), he worked on various independent and foreign projects – in which he was frequently typecast as mentally disturbed outsiders in such films as Mad Dog Morgan (1976) and The American Friend (1977) – until he found new fame for his role as an American photojournalist in Apocalypse Now (1979). He went on to helm his third directorial work Out of the Blue (1980), for which he was again honored at Cannes, and appeared in Rumble Fish (1983) and The Osterman Weekend (1983). He saw a career resurgence in 1986 when he was widely acclaimed for his performances in Blue Velvet and Hoosiers, the latter of which saw him nominated for the Academy Award for Best Supporting Actor. His fourth directorial outing came about through Colors (1988), followed by an Emmy-nominated lead performance in Paris Trout (1991). In 1990, Dennis Hopper directed The Hot Spot, which was not a box-office hit. Hopper found greater fame for portraying the villains of the films Super Mario Bros. (1993), Speed (1994) and Waterworld (1995).
Hopper's later work included a leading role in the short-lived television series Crash (2008–2009), inspired by the film of the same name. He appeared in three films released posthumously: Alpha and Omega (2010), The Last Film Festival (2016) and the long-delayed The Other Side of the Wind (2018), which had been filmed in the early 1970s.
