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: A Brooklynite from head to toe, Dane Clark never completely forsook his streetwise pugnacity, not even while attending Cornell and John Hopkins, and earning a law degree from St. John's University. Clark held down several Depression-era jobs--road gang worker, boxer, ballplayer, magazine model--before making his first stage appearance in 1938. Four years later, he made his entree into films, at first using his given name of Bernard Zanville (sometimes spelled Zaneville). Signed by Warner Bros. in 1943, Clark was given a new professional name and purpose in life: as potential replacement for Warners' resident "tenement tough" John Garfield. Since there was plenty of life left in the original Garfield, however, Clark was largely confined to secondary roles, usually as the hero's best friend or the cocky troublemaker from Brooklyn. As the 1940s drew to a close, Clark was afforded a few leading roles by Warners, though it was while on loan-out to Republic that he delivered his finest performance, as emotionally overwrought accidental murderer Danny Hawkins in Moonrise (1948). His film appearances were fewer and farther between in the 1950s, as he sought out more rewarding roles on television and the Broadway stage. He did get to play Harlem Globetrotters maven Abe Saperstein in the 1954 feature Go, Man, Go, but he also had to produce the film himself. On TV, Clark starred as news correspondent Dan Miller on the weekly adventure series Wire Service (1956), and played hotel owner Slate Shannon on the 1959 TV version of the old Bogart-Bacall radio series Bold Venture. He also co-starred as Lt. Tragg on the ill-advised New Perry Mason (1973), and made innumerable guest appearances on such series as Alfred Hitchcock Presents, The Twilight Zone, The Untouchables and Ellery Queen (1975 version).

Trivia: Connecticut native Linda Purl grew up in Japan, where her father, a Union Carbide executive, had been transferred. Under the watchful eye of her mother, a former ballerina, Purl began acting professionally in Japanese stage and TV productions at the age of seven. Ten years later, she made her American film debut in Jory (1972). Never a conventional ingenue, she has played everything from mentally retarded teens to rape victims to psychotic killers, as well as a few real-life personalities like Alice Roosevelt Longworth and globetrotting journalist Nellie Bly. Purl has the distinction of playing two different recurring characters on the same television series. During the 1974-75 season of Happy Days, she was seen as Richie Cunningham's (Ron Howard) high-school girlfriend Gloria; she returned to the series in 1982 as Ashler Pfister, a divorced mother with whom Fonzie (Henry Winkler) was briefly involved romantically. Linda has also appeared regularly on such series as The Secret Storm and Beacon Hill; more recently, she played an assistant DA put in charge of a group of young ex-convicts on the syndicated weekly adventure series Robin's Hoods (1994). Linda Purl was at one time married to Desi Arnaz Jr..
