Trivia: Lead actor, onscreen from the late '80s.

Trivia: David McCallum's parents were both members of the London Philharmonic; his mother was a cellist and his father was first violinist. The young Scots-born McCallum himself planned to pursue a musical career after serving with the Royal West African Frontier Force, but decided instead upon acting. Following his studies at the RADA, McCallum entered films in 1957, where he was usually cast as a troublemaking street punk or callow junior officer. His first American film (albeit lensed principally in England) was Freud (1962), in which he played a profoundly mother-obsessed mental patient. McCallum became the rage of the teeny-bopper set when he was cast as cool-headed Russian secret agent Ilya Kuryakin on TV's The Man From UNCLE (1964-68). At one point, McCallum was receiving far more fan mail than the series' ostensible star, Robert Vaughn; he took advantage of his celebrity to launch a brief singing career, duetting with Nancy Sinatra on the 1966 UNCLE episode "The Take Me to Your Leader Affair." He also wrote the music and lyrics and sang the title song of his 1967 movie vehicle Three Bites of the Apple. Following UNCLE, McCallum had a handful of solid dramatic film roles before returning to the small screen in the short-lived 1975 series The Invisible Man. He continued to appear primarily in episodic television, although he occasionally could be glimpsed on the big-screen as well. Highlights include The Watcher in the Woods, Matlock, The Wind, Murder She Wrote, and The A-Team. The nineties began with a major part in the sleeper Hear My Song, before continuing in Healer, Law and Order, and Cherry. McCallum became a fixture on television yet again at the beginning of the 21st century when he was cast as Donald "Ducky" Mallard on CBS' drama NCIS, which was for a time the top-rated scripted drama on network television.A man of sundry outside interests, McCallum's range of expertise includes computers and small-arms weaponry. Once wed to actress Jill Ireland, David McCallum has since 1967 been married to Katherine Carpenter.

Trivia: While growing up in Chicago, Tom Bosley dreamed of becoming the star left-fielder for the Cubs. As it turned out, the closest Bosley got to organized athletics was a sportscasting class at DePauw University. After additional training at the Radio Institute of Chicago and two years' practical experience in various dramatic radio programs and stock companies, he left for New York in 1950. Five years of odd jobs and summer-theater stints later, he landed his first off-Broadway role, playing Dupont-Dufort in Jean Anouilh's Thieves' Carnival. Steadier work followed at the Arena Theatre in Washington, D.C.; then in 1959, Bosley landed the starring role in the Broadway musical Fiorello!, picking up a Tony Award, an ANTA Award, and the New York Drama Critics Award in the bargain. In 1963, he made his film bow as Natalie Wood's "safe and secure" suitor Anthony Colombo in Love With the Proper Stranger. Occasionally cast as two-bit criminals or pathetic losers (he sold his eyes to blind millionairess Joan Crawford in the Spielberg-directed Night Gallery TV movie), Bosley was most often seen as a harried suburban father. After recurring roles on such TV series as That Was the Week That Was, The Debbie Reynolds Show, and The Sandy Duncan Show, Bosley was hired by Hanna-Barbera to provide the voice of flustered patriarch Howard Boyle on the animated sitcom Wait Til Your Father Gets Home (1972-1973). This served as a dry run of sorts for his most famous series-TV assignment: Howard Cunningham, aka "Mr. C," on the immensely popular Happy Days (1974-1983). The warm, familial ambience of the Happy Days set enabled Bosley to weather the tragic death of his first wife, former dancer Jean Elliot, in 1978. In addition to his Happy Days duties, Bosley was narrator of the syndicated documentary That's Hollywood (1977-1981). From 1989 to 1991, he starred on the weekly series The Father Dowling Mysteries, and thereafter was seen on an occasional basis as down-to-earth Cabot Cove sheriff Amos Tupper on Murder, She Wrote. Reportedly as kind, generous, and giving as his Happy Days character, Tom Bosley has over the last 20 years received numerous honors for his many civic and charitable activities.

Trivia: Angela Lansbury received an Oscar nomination for her first film, Gaslight, in 1944, and has been winning acting awards and audience favor ever since. Born in London to a family that included both politicians and performers, Lansbury came to the U.S. during World War II. She made notable early film appearances as the snooty sister in National Velvet (1944); the pathetic singer in The Picture of Dorian Gray (1945), which garnered her another Academy nomination; and the madam-with-a-heart-of-gold saloon singer in The Harvey Girls (1946). She turned evil as the manipulative publisher in State of the Union (1948), but was just as convincing as the good queen in The Three Musketeers (1948) and the petulant daughter in The Court Jester (1956). She received another Oscar nomination for her chilling performance as Laurence Harvey's scheming mother in The Manchurian Candidate (1962) and appeared as the addled witch in Bedknobs and Broomsticks (1971), among other later films. On Broadway, she won Tony awards for the musicals Mame (1966), Dear World (1969), the revival of Gypsy (1975), Sweeney Todd (1979) and, at age 82, for the play Blithe Spirit (2009). Despite a season in the '50s on the game show Pantomime Quiz, she came to series television late, starring in 1984-1996 as Jessica Fletcher in Murder, She Wrote; she took over as producer of the show in the '90s. She returned to the Disney studios to record the voice of Mrs. Potts in Beauty and the Beast (1991) and to sing the title song and later reprised the role in the direct-to-video sequel, The Enchanted Christmas (1997). Lansbury is the sister of TV producer Bruce Lansbury.

Trivia: Fresh out of New York's High School of Performing Arts, doe-eyed actress Janet Margolin was cast as an emotionally disturbed teenager in the Broadway production Daughter of Silence. Though the play didn't last long, Margolin's performance won her the similar role of a schizophrenic girl who speaks only in backward rhymes in the 1962 film David and Lisa. This award-winning assignment proved to be the high point of Margolin's career; most of her later roles (Mary of Bethany in 1965's The Greatest Story Ever Told, Gina Lollobrigida's daughter in 1968's Buona Sera Mrs. Campbell etc.) made but minimal demands on her acting skills. Better opportunities came her way in a brace of Woody Allen films, Take the Money and Run (1969) and Annie Hall (1977). On TV, Janet Margolin co-starred in the 1975 detective series Lanigan's Rabbi. Janet Margolin died of ovarian cancer at the age of 50; she was survived by her husband, actor Ted Wass.

Trivia: Often introduced as "one of America's most familiar faces," it's likely that you've caught a glimpse of Ron Masak either in one of his over 300 appearances in various television shows, on that commercial that lingers in the back of your memory somewhere (he was once blessed with the moniker "king of commercials" and was the voice of the Vlassic Pickle Stork for 15 years), or maybe in one of his 15 feature film appearances. Whatever you might recognize him from, if you don't remember his name, he's the guy that you know you've seen somewhere before, but just might not be able to place where. A native of Chicago, IL (he was once offered a contract with the Chicago White Sox by Hall-of-Famer Rogers Hornsby), Masak was classically trained as an actor at the Windy City's own CCC. A tireless performer, Masak found an initial platform for his talents in the Army, where he toured the world entertaining in an all-Army show in which he served as writer, performer, and director. Masak became well-known not only for his acting abilities, but for the fact that he was a dedicated performer who never missed a show. Proving himself adept at roles ranging from Shakespeare to his almost decade-long stint as the sheriff on Murder She Wrote, Masak thrived in theater and in commercial work around Chicago in the late '50s and early '60s.After a few minor roles in such television series as Bewitched, I Dream of Jeannie, The Monkees, and The Flying Nun (not to mention what many consider to be one of the earliest Elvis impersonations on the Spade Cooley Show in 1958), Masak was spotted by producer Harry Ackerman early in his career and went to California to audition for a lead in a pilot. Though that particular prospect fell through, Masak was introduced to John Sturges, a meeting which resulted in his feature debut in the cold-war thriller Ice Station Zebra (1968). Masak's work as an emcee is another testament to his universal appeal and versatile likeability; he has served as host for some of the biggest names in show business, including such talents as Kenny Rogers and Billy Crystal. Masak also starred in four of the most successful sales motivational videos of all time, including Second Effort with Vince Lombardi and Ya Gotta Believe with Tommy Lasorda (which Masak also wrote and directed). The first recipient of MDA's Humanitarian of the Year Award, Masak's work as field announcer for the Special Olympics and his eight-year stint as host of The Jerry Lewis Telethon represents only a fraction of his remarkable work as a compassionate philanthropist, and though Masak's film work may not be as prolific or as frequent as his extensive television work, his roles in such films as Tora! Tora! Tora! (1970) are always memorable and constantly ring true with an appeal that often leaves a lasting impression, even though his screen time may be brief and his characters secondary.

Trivia: American actor Cliff Potts began his career billed under his real name of Cliff Potter. After featured parts in films like Man Called Gannon (1969), Silent Running (1971) and The Groundstar Conspiracy (1972), Potts essayed the title character in the 1972 independent film Cry for Me Billy. His TV movie roles include Cole Younger in 1980's Belle Starr. Cliff Potts was also a regular on several weekly series: he played John Brooke in the 1979 video adaptation of Little Women, and was seen as ex-baseball player Ted McCovey, the new husband of reporter Billie Newman (Linda Kelsey), during the 1981-82 season of Lou Grant.
