Trivia: It had originally been the hope of Walter Brennan (and his family) that he would follow in the footsteps of his father, an engineer; but while still a student, he was bitten by the acting bug and was already at a crossroads when he graduated in 1915. Brennan had already worked in vaudeville when he enlisted at age 22 to serve in World War I. He served in an artillery unit and although he got through the war without being wounded, his exposure to poison gas ruined his vocal chords, leaving him with the high-pitched voice texture that made him a natural for old man roles while still in his thirties. His health all but broken by the experience, Brennan moved to California in the hope that the warm climate would help him and he lost most of what money he had when land values in the state collapsed in 1925. It was the need for cash that drove him to the gates of the studios that year, for which he worked as an extra and bit player. The advent of the talkies served Brennan well, as he had been mimicking accents in childhood and could imitate a variety of different ethnicities on request. It was also during this period that, in an accident during a shoot, another actor (some stories claimed it was a mule) kicked him in the mouth and cost him his front teeth. Brennan was fitted for a set of false teeth that worked fine, and wearing them allowed him to play lean, lanky, virile supporting roles; but when he took them out, and the reedy, leathery voice kicked in with the altered look, Brennan became the old codger with which he would be identified in a significant number of his parts in the coming decades. He can be spotted in tiny, anonymous roles in a multitude of early-'30s movies, including King Kong (1933) (as a reporter) and one Three Stooges short. In 1935, however, he was fortunate enough to be cast in the supporting role of Jenkins in The Wedding Night. Directed by King Vidor and produced by Samuel Goldwyn, it was supposed to launch Anna Sten (its female lead) to stardom; but instead, it was Brennan who got noticed by the critics. He was put under contract with Goldwyn, and was back the same year as Old Atrocity in Barbary Coast. He continued doing bit parts, but after 1935, his films grew fewer in number and the parts much bigger. It was in the rustic drama Come and Get It (1936) that Brennan won his first Academy Award as Best Supporting Actor. Two years later, he won a second Best Supporting Actor Oscar for his performance in Kentucky (1938). That same year, he played major supporting roles in The Texans and The Buccaneer, and delighted younger audiences with his moving portrayal of Muff Potter, the man wrongfully accused of murder in Norman Taurog's The Adventures of Tom Sawyer. Brennan worked only in high-profile movies from then on, including The Story of Vernon and Irene Castle, Stanley and Livingston, and Goldwyn's They Shall Have Music, all in 1939. In 1940, he rejoined Gary Cooper in The Westerner, playing the part of a notoriously corrupt judge. Giving a beautifully understated performance that made the character seem sympathetic and tragic as much as dangerous and reprehensible, he won his third Best Supporting Actor award. There was no looking back now, as Brennan joined the front rank of leading character actors. His ethnic portrayals gradually tapered off as Brennan took on parts geared specifically for him. In Frank Capra's Meet John Doe and Howard Hawks' Sergeant York (both 1941), he played clear-thinking, key supporting players to leading men, while in Jean Renoir's Swamp Water (released that same year), he played another virtual leading role as a haunted man driven by demons that almost push him to murder. He played only in major movies from that point on, and always in important roles. Sam Wood used him in Goldwyn's The Pride of the Yankees (1942), Lewis Milestone cast him as a Russian villager in The North Star (1943), and he was in Goldwyn's production of The Princess and the Pirate (1944) as a comical half-wit who managed to hold his own working alongside Bob Hope. Brennan played the choice role of Ike Clanton in Ford's My Darling Clementine (1946) and reprised his portrayal of an outlaw clan leader in more comic fashion in Burt Kennedy's Support Your Local Sheriff some 23 years later. He worked with Cooper again on Delmer Daves' Task Force (1949) and played prominent roles in John Sturges' Bad Day at Black Rock and Anthony Mann's The Far Country (both 1955). In 1959, the 64-year-old Brennan got one of the biggest roles of his career in Hawks' Rio Bravo, playing Stumpy, the game-legged jailhouse keeper who is backing up the besieged sheriff. By that time, Brennan had moved to television, starring in the CBS series The Real McCoys, which became a six-season hit built around his portrayal of the cantankerous family patriarch Amos McCoy. The series was such a hit that John Wayne's production company was persuaded to release a previously shelved film, William Wellman's Goodbye, My Lady (1956), about a boy, an old man (played by Brennan), and a dog, during the show's run. Although he had disputes with the network and stayed a season longer than he had wanted, Brennan also liked the spotlight. He even enjoyed a brief, successful career as a recording artist on the Columbia Records label during the 1960s. Following the cancellation of The Real McCoys, Brennan starred in the short-lived series The Tycoon, playing a cantankerous, independent-minded multimillionaire who refuses to behave the way his family or his company's board of directors think a 70-year-old should. By this time, Brennan had become one of the more successful actors in Hollywood, with a 12,000-acre ranch in Northern California that was run by his sons, among other property. He'd invested wisely and also owned a share of his first series. Always an ideological conservative, it was during this period that his political views began taking a sharp turn to the right in response to the strife he saw around him. During the '60s, he was convinced that the anti-war and civil rights movements were being run by overseas communists -- and said as much in interviews. He told reporters that he believed the civil rights movement, in particular, and the riots in places like Watts and Newark, and demonstrations in Birmingham, AL, were the result of perfectly content "Negroes" being stirred up by a handful of trouble-makers with an anti-American agenda. Those on the set of his last series, The Guns of Will Sonnett -- in which he played the surprisingly complex role of an ex-army scout trying to undo the damage caused by his being a mostly absentee father -- say that he cackled with delight upon learning of Martin Luther King Jr.'s assassination in 1968. Brennan later worked on the 1972 presidential campaign of reactionary right-wing California Congressman John Schmitz, a nominee of the American Party, whose campaign was predicated on the notion that the Republican Party under Richard Nixon had become too moderate. Mostly, though, Brennan was known to the public for his lovable, sometimes comical screen persona, and was still working as the '60s drew to a close, on made-for-TV movies such as The Over-the-Hill Gang, which reunited him with one of his favorite directors, Jean Yarbrough, and his old stablemate Chill Wills. Brennan died of emphysema in 1974 at the age of 80.

Trivia: Actor Dack Rambo specialized in low-budget action features and television. Born Norman Rambo and the twin brother of actor Dirk Rambo, he started out playing Dack Massey on The New Loretta Young Show (1962-1963). He next appeared as Grant Harrison on the daytime soap Another World and in the early '80s as Steve Jacoby on All My Children. Between 1985 and 1988, Rambo played Jack Ewing on the nighttime serial Dallas. He has also appeared regularly on series such as The Guns of Will Sonnett (1967-1969). Rambo made his feature-film debut in Which Way to the Front (1970). He made his last film appearance in the 1992 film Ultra Warrior.

Trivia: Though he could pass as a good-natured cabbie or down-to-earth dockworker with his chiseled features and gravelly voice, J.D. Cannon has played more than his share of villains, some of them psychotic in nature. A stage actor in the 1950s and 1960s, Cannon was first seen on the big screen in 1966's The American Dream. His breakthrough role in films was road-gang convict Society Red in Cool Hand Luke (1967). On television, J. D. Cannon was seen as hard-nosed Chief of Detectives Peter B. Clifford on the Dennis Weaver series McCloud (1970-77), and as General Hampton on Call to Glory (1985).

Trivia: The odyssey of Dennis Hopper was one of Hollywood's longest, strangest trips. A onetime teen performer, he went through a series of career metamorphoses -- studio pariah, rebel filmmaker, drug casualty, and comeback kid -- before finally settling comfortably into the role of character actor par excellence, with a rogues' gallery of killers and freaks unmatched in psychotic intensity and demented glee. Along the way, Hopper defined a generation, documenting the shining hopes and bitter disappointments of the hippie counterculture and bringing their message to movie screens everywhere. By extension, he spearheaded a revolt in the motion picture industry, forcing the studio establishment to acknowledge a youth market they'd long done their best to deny. Born May 17, 1936 in Dodge City, Kansas, Hopper began acting during his teen years, and made his professional debut on the TV series Medic. In 1955 he made a legendary collaboration with the director Nicholas Ray in the classic Rebel Without a Cause, appearing as a young tough opposite James Dean. Hopper and Dean became close friends during filming, and also worked together on 1956's Giant. After Dean's tragic death, it was often remarked that Hopper attempted to fill his friend's shoes by borrowing much of his persona, absorbing the late icon's famously defiant attitude and becoming so temperamental that his once-bright career quickly began to wane. Seeking roles far removed from the stereotypical 'troubled teens' which previously dotted his resume, Hopper began training with the Actors Studio. However, on the set of Henry Hathaway's From Hell to Texas he so incensed cast and crew with his insistence upon multiple takes for his improvisational techniques -- the reshoots sometimes numbering upwards of 100 -- that he found himself a Hollywood exile. He spent much of the next decade mired in "B"-movies, if he was lucky enough to work at all. Producers considered him such a risk that upon completing 1960's Key Witness he did not reappear on-screen for another three years. With a noteworthy role in Hathaway's 1965 John Wayne western The Sons of Katie Elder, Hopper made tentative steps towards a comeback. He then appeared in a number of psychedelic films, including 1967's The Trip and the following year's Monkees feature Head, and earned a new audience among anti-establishment viewers.With friends Peter Fonda and Jack Nicholson in front of the camera, Hopper decided to direct his own movie, and secured over $400,000 in financing to begin filming a screenplay written by novelist Terry Southern. The result was 1969's Easy Rider, a sprawling, drug-fueled journey through an America torn apart by the conflict in Vietnam. Initially rejected by producer Roger Corman, the film became a countercultural touchstone, grossing millions at the box office and proving to Hollywood executives that the ever-expanding youth market and their considerable spending capital would indeed react to films targeted to their issues and concerns, spawning a cottage industry of like-minded films. Long a pariah, Hopper was suddenly hailed as a major new filmmaker, and his success became so great that in 1971 he appeared in an autobiographical documentary, American Dreamer, exploring his life and times.The true follow-up to Easy Rider, however, was 1971's The Last Movie, an excessive, self-indulgent mess that, while acclaimed by jurors at the Venice Film Festival, was otherwise savaged by critics and snubbed by audiences. Once again Hopper was left picking up the pieces of his career; he appeared only sporadically in films throughout the 1970s, most of them made well outside of Hollywood. His personal life a shambles -- his marriage to singer/actress Michelle Phillips lasted just eight days -- Hopper spent much of the decade in a haze, earning a notorious reputation as an unhinged wild man. An appearance as a disturbed photojournalist in Francis Ford Coppola's Apocalypse Now did little to repair most perceptions of his sanity. Then in 1980, Hopper traveled to Canada to appear in a small film titled Out of the Blue. At the outset of the production he was also asked to take over as director, and to the surprise of many, the picture appeared on schedule and to decent reviews. Slowly he began to restake his territory in American films, accepting roles in diverse fare ranging from 1983's teen drama Rumble Fish to the 1985 comedy My Science Project. In 1986 Hopper returned to prominence with a vengeance. His role as the feral, psychopathic Frank Booth in David Lynch's masterpiece Blue Velvet was among the most stunning supporting turns in recent memory, while his touching performance as an alcoholic assistant coach in the basketball drama Hoosiers earned an Academy Award nomination. While acclaimed turns in subsequent films like 1987's The River's Edge threatened to typecast Hopper, there was no doubting his return to Hollywood's hot list, and in 1988 he directed Colors, a charged police drama starring Sean Penn and Robert Duvall. While subsequent directorial efforts like 1989's Chattahoochee and 1990's film noir The Hot Spot failed to create the same kind of box office returns as Easy Rider over two decades earlier, his improbable comeback continued throughout the 1990s with roles in such acclaimed, quirky films as 1993's True Romance and 1996's Basquiat. Hopper was also the villain-du-jour in a number of Hollywood blockbusters, including 1994's Speed and the following year's Waterworld, and was even a pitchman for Nike athletic wear. He also did a number of largely forgettable films such asRon Howard's EdTV (1999). In addition, he also played writer and Beat extraordinaire William S. Burroughs in a 1999 documentary called The Source with Johnny Depp as Jack Kerouac and John Turturro as Allen Ginsberg. In 1997 Hopper was awarded the distinction of appearing 87th in Empire Magazine's list of "The Top 100 Movie Stars of All Time."Hopper contracted prostate cancer in the early 2000s, and died of related complications in Venice, CA, in late May 2010. He was 74 years old.
