Trivia: Like Clark Gable, David Janssen lost quite a few film roles in the early stages of his career because his ears were "too big" and -- also like Gable-- he did pretty well for himself in the long run. The son of a former beauty queen-cum-stage mother, Janssen was virtually strong-armed into show business, appearing as a child actor on-stage and as a juvenile performer in such films as Swamp Fire (1946). Signed to a Universal contract in 1950, he showed up fleetingly in films both big-budget (To Hell and Back) and small (Francis Goes to West Point). Full stardom eluded Janssen until 1957, when he was personally selected by actor/producer Dick Powell to star in the TV version of Powell's radio series Richard Diamond, Private Detective. Though he didn't exactly become a millionaire (for several years he earned a beggarly 750 dollars per week), Janssen's saleability soared as a result of his three-year Diamond gig, and by 1960 he was earning top billing in such Allied Artists productions as King of the Roaring 20s (1960), in which he played gambler Arnold Rothstein, and Hell to Eternity (1960). In 1963, he landed his signature role of Dr. Richard Kimble on TV's The Fugitive. For the next four years, Janssen/Kimble perambulated throughout the country in search of the "one-armed man" who committed the murder for which Kimble was sentenced to death, all the while keeping one step ahead of his dogged pursuer, Lieutenant Gerard (Barry Morse). The final episode of The Fugitive, telecast in August of 1967, was for many years the highest-rated TV episode in history. There was little Janssen could do to top that, though he continued appearing in such films as Warning Shot (1967) and Green Berets (1969), and starring in such TV series as O'Hara, U.S. Treasury (1971) and Harry O (1974-1976). David Janssen died of a sudden heart attack at age 49, not long after completing his final TV movie, City in Fear (1980).

Trivia: The son of a London shopkeeper, Barry Morse enrolled at the Royal Academy of Dramatic Arts at age 15. Upon graduation, Morse spent four years in provincial repertory, playing (by his own count) some 300 roles. In 1942 he made his first film appearance in Will Hays's The Goose Steps Out. Firmly established in London theatrical circles by 1951, he starred in an early BBC telecast of Hamlet--then left for Canada, where he would spend the next decade. Dubbed "the Laurence Olivier of Canada" by more than one admirer, Morse appeared with regularity on the CBC, occasionally producing and directing as well. He began dividing his time between Toronto and Hollywood in 1959, showing up in such American TV anthologies as Playhouse 90 and The Twilight Zone. In 1963, he was hired by producer Quinn Martin to play the diligent Lieutenant Girard in the popular weekly series The Fugitive. Morse's post-Fugitive television work includes two weekly series, The Adventurer (1974) and Space: 1999 (1975-77), and any number of specials and miniseries. Barry Morse's best performances of the past two decades include his interpretation of Menachem Begin in the American miniseries Sadat (1980) and his hilarious turn as a numbskull American president (who happens to be a former movie actor!) in the London Weekend Television black comedy Whoops Apocalypse (1982). Morse died in February 2008 at age 89.

Trivia: Lead actress, onscreen from the '50s.

Trivia: Marian Ross dreamed of stardom from childhood, going so far as to change the spelling of her first name to Marion because she thought it would look nicer on a marquee. When her family moved from Minnesota to California, the 16-year-old aspiring actress plunged into the busy world of amateur theatricals in the San Diego area. She was voted Outstanding Actress at San Diego State University in 1950, then went on to work at the prestigious La Jolla Playhouse. Mel Ferrer, La Jolla's resident director, recommended that Ross try her luck in Hollywood. She worked steadily in TV and films from 1953 onward, but stardom was still outside her reach. Ross played a succession of maids, nuns, nurses, and that nebulous classification, the Heroine's Best Friend. She showed up in small roles in such films as Forever Female (1953), Lust for Life (1955), and Operation Petticoat (1959), earning the respect of her fellow workers but very little in the way of public recognition. "I've always had a way of not attracting attention," she would note with resignation later in life. On television, Marion played unstressed recurring roles on such series as Life with Father, Mrs. G Goes to College and Mr. Novak. She finally achieved stardom as Marion Cunningham, mother of 1950s high-schooler Richie Cunningham, on the weekly sitcom Happy Days. What started out as a shaky midseason replacement in January of 1974 ended up ABC's number-one hit; Ross hitched her wagon to the ever-rising Happy Days star until its final episode in 1983. During this period, she reactivated her stage career, with considerably more success than she'd enjoyed in the 1950s. Ross' post-Happy Days TV gigs included a 1986 guest shot as the new bride of Captain Stubing (Gavin MacLeod) on The Love Boat and the brief 1989 series Living Dolls. In 1991, Marion Ross earned an Emmy nomination for her portrayal of archetypal Jewish mother Sophie Berger on the TV "dramedy" Brooklyn Bridge. In the decades to come, Ross would find ongoing success with recurring roles on TV series like The Drew Carey Show and Gilmore Girls, as well as providing voice acting for animated series such as SpongeBob SquarePants and Handy Manny.

Trivia: Tousle-haired Tommy Rettig was 5 years old when he was cast opposite Mary Martin in the touring version of Annie Get Your Gun. Rettig was first seen on screen in 1950, playing Richard Widmark's son in Panic in the Streets. The youngster's most celebrated screen role was the mischievous piano-playing protagonist in the Dr. Seuss-inspired fantasy The 5000 Fingers of Dr. T (1953). When Brandon de Wilde proved unavailable for the role of Jeff Martin on the upcoming TV series Lassie in 1954, Rettig was among the hundreds of juvenile actors who auditioned for the part. The producers narrowed the casting down to three hopefuls, then allowed Lassie herself to make the final decision; the noble collie instantly walked over to Rettig and affectionately nuzzled the boy. Rettig remained with Lassie for 103 episodes; when he outgrew the role in 1957, he was replaced by Jon Provost as Timmy Martin. In the wake of Lassie, the teen-aged Rettig received several guest-star assignments, but these had dried up by the early 1960s. Rettig worked as a salesman and disc jockey before being cast in the 1966 TV daytime drama Never Too Young, in which he appeared with another ex-child star, Leave It to Beaver's Tony Dow. After this brief spurt of activity, Rettig retired to the life of a farmer. In the 1970s, he went on to work as a drug addiction counselor and later as the head of his own successful computer software service. In 1990, Rettig was invited to make a showbiz comeback as director of the syndicated TV series The New Lassie -- which co-starred his successor on the old Lassie, Jon Provost. Tommy Rettig died in his Marina del Rey home of unknown causes at the age of 54.

Trivia: Down-to-earth American actor Charles Aidman brought his "everyman" personality to such realistic war films as Pork Chop Hill (1959) and War Hunt (1962). He has since been cast in roles of quiet unstressed authority in films like Countdown (1967), Twilight's Last Gleaming (1977) and Uncommon Valor (1983). Aidman has also guest-starred on practically every TV series ever made; comedy fans will remember his portrayal of the hypnotist who plants an embarrassing post-hypnotic suggestion in the mind of Rob Petrie on a 1963 Dick Van Dyke Show episode. From 1985 through 1987, Charles Aidman was narrator of the revived Twilight Zone TV anthology series.
