Trivia: Brooklyn-born actor John Joseph Patrick Ryan borrowed his stage name "Jack Lord" from a distant relative. Spending his immediate post-college years as a seafaring man, Lord worked as an engineer in Persia before returning to American shores to manage a Greenwich Village art school and paint original work; he flourished within that sphere (often signing his paintings "John J. Ryan,") and in fact exhibited the tableaux at an array of prestigious institutions including the Metropolitan Museum of Art and the Modern Museum of Art. Lord switched to acting in the late 1940s, studying under Sanford Meisner at New York's Neighborhood Playhouse. In films and television from 1949, Lord (a performer with stark features including deep-set eyes and high cheekbones) played his share of brutish villains and working stiffs before gaining TV fame as star of the critically acclaimed but low-rated rodeo series Stoney Burke (1962). At around the same time, Lord played CIA agent Felix Leiter in the first James Bond film, Dr. No. From 1968 through 1980, Lord starred on the weekly cop drama Hawaii Five-O; producers cast him as Steve McGarrett, a troubleshooter with the Hawaii State Police who spent his days cruising around the islands, cracking open individual cases, and taking on the movers and shakers in Hawaiian organized crime, particularly gangster Wo Fat (Khigh Dhiegh), who eluded capture until the program's final month on the air. Lord also wrote and directed several episodes. After Hawaii 5-0 folded, Jack Lord attempted another Hawaii-based TV series, but M Station: Hawaii (1980) never got any farther than a pilot film. Lord died of congestive heart failure in his Honolulu beachfront home at the age of 77, in January 1998. He was married to Marie Denarde for 50 years.

Trivia: American actor James MacArthur was the adopted son of stage legend Helen Hayes and playwright Charles MacArthur. Despite his mother's insistence that James have a normal childhood, it was difficult not to be intoxicated by the theatre when growing up around the greatest acting and literary talent in the '40s. At age 8, young MacArthur appeared in a stock-company production of The Corn is Green. Fresh out of Harvard, MacArthur became a movie juvenile, specializing in tortured-teen roles in such films as The Young Stranger (1957) and Disney's Light in the Forest (1958). Outgrowing his somewhat charming awkwardness, MacArthur was less satisfying as a standard leading man, and by 1967 he was wasting away in pictures like The Love Ins. That same year, the pilot film for a new Jack Lord cop series, Hawaii Five-O, was screened for a test audience. The group liked the film but not the young man (Tim O'Kelly) who played Lord's assistant, deeming him too young for the part. Hawaii producer Leonard Freeman then called upon 30-year-old MacArthur, with whom Freeman had worked on the Clint Eastwood vehicle Hang 'Em High. From 1968 through 1979, MacArthur played Hawaii Five-0's detective Danny Williams, always handy whenever Jack Lord felt the need to snap "Book 'em, Danno." Though the series enriched MacArthur and made him a vital member of the Honolulu society and business world, the actor finally packed it in after 11 seasons, when it seemed as though he'd be Danno forever (the show continued for one more season). Too wealthy to care about a career at this point, James MacArthur still took an occasional role into the '80s; his most prominent post-Hawaii assignment was the 1980 TV movie Alcatraz: The Whole Shocking Story, in which he played a rare non-sympathetic character. MacArthur died in October 2010 of natural causes at age 72.

Trivia: Following an apprenticeship in regional theater in his native Australia, Murray Matheson first appeared on the London stage in 1935's And on We Go. His first film was 1945's The Way to the Stars. Matheson's brittle acting style was somewhat reminiscent of Noel Coward and Cyril Ritchard (whom Matheson closely resembled); accordingly, most of his film and TV roles were cut from the Coward/Ritchard waspish, epigrammatic cloth. His many roles included an amusing turn as business executive Benjamin Barton David Ovington (BBDO) in the 1967 film version of How to Succeed in Business Without Really Trying, and the recurring role of bookstore proprietor Felix Mulholland on the 1972 TV series Banacek. Murray Matheson also played The Clown in the memorable 1961 Twilight Zone episode "Six Characters in Search of an Exit"; ironically, Matheson's last appearance was in the "Kick the Can" segment of Twilight Zone: The Movie (1985).

Trivia: The daughter of actor John Mills and novelist-playwright Mary Hayley Bell and the sister of actress Hayley Mills, she first appeared onscreen as an 11-week-old baby in her father's film In Which We Serve (1942), which was co-directed by her godfather, Noel Coward. Before the age of ten she acted in two more of her father's films. Her first adult role (and lead role) was in No, My Darling Daughter (1961), after which her film work was intermittent; she was rarely onscreen after the mid '70s. Her main focus has been the stage, mostly in London and occasionally on Broadway. She starred in the TV sitcom Nanny and the Professor and starred in a number of TV productions, winning an Emmy for her work in the TV movie QB VII (1975). She is married to actor Maxwell Caulfield, who is 18 years her junior.

Trivia: Dan O'Herlihy studied architecture at the National University of Ireland, but his heart was in the acting highlands. After racking up stage credits with the Gate Theater and the Abbey Players, O'Herlihy turned to films in 1946, impressing critics and filmgoers alike with his breakthrough role in Odd Man Out. He made his American movie bow in Orson Welles' MacBeth (1948), playing the not inconsiderable role of MacDuff; shortly thereafter, he appeared with his MacBeth co-star Roddy MacDowall in an economically budgeted adaptation of Robert Louis Stevenson's Kidnapped. In 1952, he earned an Academy Award nomination for his near-solo starring turn in Luis Bunuel's The Adventures of Robinson Crusoe. Maturing into a versatile character player, he could also be seen as FDR in MacArthur (1977), the frothing-at-the-mouth villain in Halloween 3: Season of the Witch (1983), a benign lizardlike alien in The Last Starfighter (1984), and the dark-purposed cyborg-firm exec in the RoboCop films. His TV credits include blarney-spouting Doc McPheeters in The Travels of Jamie McPheeters (1963), town boss Will Varner in The Long Hot Summer (1965), "The Director" in A Man Called Sloane (1979), intelligence agent Carson Marsh in Whiz Kids (1984), and Andrew Packard in Twin Peaks (1990). Dan O'Herlihy was the brother of director Michael O'Herlihy.
