Trivia: He won five gold medals as a swimmer at the 1924 and 1928 Olympics, setting many free-style records. Weissmuller appeared in several sports shorts, then was hired by MGM to play Tarzan onscreen. Beginning in 1932, he starred in 12 "Tarzan" adventures, meanwhile doing almost no other film work. In the late '40s he quit "Tarzan" and began starring in a new series, "Jungle Jim," while occasionally appearing in other films through the mid '50s, after which he retired from acting. He was married six times. His stormy marriage to actress Lupe Velez (1933-38) received much coverage in scandal sheets. He authored an autobiography, Water, World and Weissmuller (1967).

Trivia: Educated in London and Paris, the breathtakingly beautiful Maureen O'Sullivan was discovered for films by director Frank Borzage while both were attending a horse show in Dublin. She made her screen debut in 1930 opposite Irish tenor John McCormick in Song O' My Heart, which earned her a contract with Fox studios. After appearing in such Fox blockbusters as Just Imagine (1930) and A Connecticut Yankee (1931), she moved to MGM, where her first assignment was the role of Jane Parker in Tarzan the Ape Man (1932). She repeated this characterization in Tarzan and His Mate (1934), causing a minor sensation with her bikini-like costume and a nude swimming scene. Somewhat more modestly garbed, she went on to co-star in four more Tarzan pictures over the next eight years. Though MGM kept her busy in a variety of films, ranging from such costume dramas as The Barretts of Wimpole Street (1934) and David Copperfield (1935) to the Marx Brothers' A Day at the Races (1937), she is best remembered for her appearances as Jane, a fact that has been a source of both pride and irritation for the actress (she liked her co-star Johnny Weissmuller but despised Cheeta the chimpanzee, who bit her more than once). She retired from films in 1942 to devote her time to her husband, director John Farrow, and her many children, two of whom grew up to be actresses Mia Farrow and Tisa Farrow. She returned to the screen in 1948, averaging a film every two years until 1958. An early arrival on TV, she hosted a local children's program in New York and the syndicated series Irish Heritage, and in 1964 was hired by NBC to co-anchor The Today Show (her replacement the following year was Barbara Walters). In 1964 she starred with Paul Ford in the Broadway production Never Too Late, playing a fortysomething suburbanite who suddenly finds herself pregnant; the following year she and Ford repeated their roles in the screen version. Widowed in 1963, she remarried 20 years later, sporadically reviving her screen activities in such films as Hannah and Her Sisters (1985), in which she and Lloyd Nolan played the combative parents of her real-life daughter Mia Farrow. As regally beautiful as ever, Maureen O'Sullivan showed up again on TV in the mid-'90s as one of the interviewees in a Tarzan retrospective.

Trivia: Child star Johnny Sheffield was the son of British actor Reginald Sheffield, himself a former juvenile performer (he played the title role in the 1913 cinemazation of David Copperfield). A wan, sickly infant, Johnny's health and physical stamina was beefed up by a strict exercise regimen supervised by his father. At age 7, Johnny co-starred in the original Broadway production of On Borrowed Time. This brought the young actor to the attention of the MGM casting department, which was looking for a suitably athletic child to play Boy in the studio's Tarzan pictures. Beginning with 1939's Tarzan Finds a Son, Sheffield played Boy in eight "Tarzan" programmers, remaining with the series when it shifted its base of operations from MGM to RKO. After a brief period of unemployment, the 17-year-old Sheffield was cast as the lead in Monogram's Bomba the Jungle Boy series, which endured for three years and twelve low-budget pictures. Sheffield decided to retire from acting in 1955. He sank his film earnings into real estate -- growing quite wealthy in the process -- and enrolled as a pre-med student at UCLA. When last heard from, Sheffield was living in happy retirement, overseeing his numerous real estate holdings. Johnny Sheffield's film credits should not be confused with those of British character actor John Sheffield.

Trivia: American actress Laraine Day, born Laraine Johnson, a descendant of a prominent Mormon pioneer leader, moved with her family from Utah to California, where she began her acting career with the Long Beach Players. In 1937 she debuted onscreen in a bit part in Stella Dallas; shortly afterwards she won lead roles in several George O'Brien westerns at RKO, in which she was billed as "Laraine Hays" and then "Laraine Johnson." In 1939 she signed with MGM, going on to become popular and well-known (billed as "Laraine Day") as Nurse Mary Lamont, the title character's fiancee in a string of seven "Dr. Kildare" movies beginning with Calling Dr. Kildare (1939); Lew Ayres played Dr. Kildare. During the '40s and '50s she played a variety of leads in medium-budget films made by several studios. She rarely appeared in films after 1960, but later occasionally appeared on TV, portraying matronly types. She was married to famous baseball player Leo Durocher from 1947-60, when she was sometimes referred to as "the first lady of baseball." Her first husband was singer Ray Hendricks, and her third, TV producer Michael Grilkhas. She is the author of a book of memoirs, Day With Giants (1952), and an inspirational book, The America We Love; in the '70s she was the official spokeswoman for the Make America Better program of the National Association of Real Estate Boards, traveling across the country speaking on environmental issues. Day died at age 87 in November 2007.

Trivia: Like his fellow character actors C. Aubrey Smith and Sir Guy Standing, the dignified Henry Stephenson was seemingly born with a relief map of the British Empire chiseled on his countenance. Born in the British West Indies, Stephenson was educated at England's Rugby College. He turned to acting in his twenties, touring the provinces before settling into leading roles in London and New York. Though he made a smattering of silent film appearances, Stephenson's movie career did not really begin until 1932, with his supporting appearance in The Animal Kingdom. Virtually always cast as an aristocrat or man of means, Stephenson essayed such roles as Mr. Laurence in Little Women (1933), Sir Joseph Banks in Mutiny on the Bounty (1935), the Duke of Norfolk in The Prince and the Pauper, and Count Matthieu de Lesseps in Suez (1938). Henry Stephenson acted in films until his mid-seventies; his last film assignments included the part of Mr. Brownlow in the David Lean-directed Oliver Twist (1948).

Trivia: The daughter of an actress (Elaine Inescort) and a British journalist, Frieda Inescort learned the intricacies of High Society on a first-hand basis as the personal secretary of Lady Astor. Thus it was hardly surprising that Inescort would specialize in playing haughty grande dames when she went into acting. She made her first Broadway appearance in the 1922 production The Truth About Blayds, then went on to appear in a number of Shaw plays. In films from 1935 to 1960, she was at her imperious best as Miss Bingley in Pride and Prejudice. Multiple sclerosis forced Frieda Inescort into an all-too-early retirement.

Trivia: Chiselled-featured leading man Henry Wilcoxon was born in the West Indies to British parents. He cut his theatrical teeth with the prestigious Birmingham Repertory Theater, then went on to play several leads in London. While starring in the stage play Eight Bells, Wilcoxon was selected to play Marc Antony in Cecil B. DeMille's Cleopatra (1934). Thus began a 25-year association with DeMille, during which time Wilcoxon functioned as actor, casting director, associate producer, producer, and close friend. When asked by interviewer Leonard Maltin about his experiences with C.B., Wilcoxon replied genially, "Does your tape last about ten hours?" Outside of the DeMille orbit, Henry Wilcoxon played leading and character parts in such films as The Last of the Mohicans (1936), If I Were King (1938), Tarzan Finds a Son (1939), Mrs. Miniver (1942) (as the jingoistic minister), A Connecticut Yankee in King Arthur's Court (1949), The War Lord (1965), and FIST (1978); he also worked extensively in television, guest starring on such programs as I Spy and Marcus Welby, M.D..

Trivia: Though he frequently adopted a British accent, actor Gavin Muir was a Chicago boy. After stage work, Muir went to Hollywood for Mary of Scotland (1936), then spent the next quarter century menacing various stars as sly, slow-speaking villains. His indeterminate nationality made him useful in war films like The Master Race (1945), while his tendency to look as though he was hiding some awful secret enabled him to shine in such melodramas as Nightmare (1942). A more benign but still not altogether above-board Muir appeared in the role of a scientist coerced into inflicting invisibility upon Arthur Franz in Abbott and Costello Meet the Invisible Man (1951). As late as 1959, Muir was throwing roadblocks in the way of sweetness 'n' light as a snooty butler on TV's The Betty Hutton Show. Gavin Muir's last film before slipping into retirement was Night Tide (1963), an appropriately glum ghost story.

Trivia: A solid, good-looking leading man with an upper-class British accent, he moved to England while in his teens and joined the army in 1917, serving in France. He debuted onstage in 1919, then onscreen in 1924; for the next decade he alternated between plays and films, usually as a leading man, then moved to Hollywood in 1934 and appeared in many American films. He was often cast as an upright, conscientious husband, lover, or friend. He returned to England for war service in 1942. After the war he continued to perform in British plays and films for the next two decades.
