Trivia: Few of the performers in director John Ford's How Green Was My Valley (1941) were as qualified to appear in the film as Rhys Williams. Born in Wales and intimately familiar from childhood with that region's various coal-mining communities, the balding, pug-nosed Williams was brought to Hollywood to work as technical director and dialect coach for Ford's film. The director was so impressed by Williams that he cast the actor in the important role of Welsh prize fighter Dai Bando. Accruing further acting experience in summer stock, Rhys Williams became a full-time Hollywood character player, appearing in such films as Mrs. Miniver (1942), The Spiral Staircase (1946), The Inspector General (1949), and Our Man Flint (1966).

Trivia: Though he has logged many impressive credits as an actor, Vienna-born Theodore Bikel preferred to think of himself -- and bill himself -- as a folksinger. Emigrating to Palestine in the 1930s, Bikel supported himself with his music, and also acted with Tel Aviv's Habimah Theatre in Sholem Alecheim's Tevye the Milkman. A quick study in several languages, Bikel honed his acting skills with Britain's Royal Academy of Dramatic Art. Three years after his London stage debut, Bikel made his first film, playing a German naval officer (the first of many villainous roles) in The African Queen (1951). In 1958, he was nominated for an Oscar for his supporting appearance in The Defiant Ones. One year later, he costarred with Mary Martin on Broadway, originating the role of Captain Von Trapp in Rodgers and Hammerstein's The Sound of Music. Active in many political causes ranging from Jewish relief to the Democratic Party, Bikel served as president of Actor's Equity from 1973 until 1982. In a mid-1980s interview, Theodore Bikel noted with amusement that, in spite of his many stage and screen appearances, many fans remembered him best for his brief unsympathetic appearance as a Russian officer in the otherwise forgettable 1957 film Fraulein. Bikel continued working well into his advanced years, both on screen and on stage. He died in 2015, at age 91.

Trivia: Torin Thatcher came out of a military family in India to become a top stage actor in England and a well-known character actor in international films and television. Born Torin Herbert Erskine Thatcher in Bombay, India, in 1905, he was the great-grandson and grandson of generals -- one of whom had fought with Clive -- but he planned for a quieter life; educated at Bedford School, he originally intended to become a teacher before being bitten by the acting bug. Instead, he attended the Royal Academy of Dramatic Art, and later worked in every kind of theatrical production there was, from Greek tragedy to burlesque. Thatcher made his London debut in 1927 as Tranio in a production of The Taming of the Shrew with the Old Vic Company, and he subsequently portrayed both the Ghost and Claudius in Hamlet with the same company. In the years that followed, Thatcher was in more than 50 Shakespearean productions and 20 plays by George Bernard Shaw. The outbreak of the Second World War took Thatcher into uniform, and he served for six years in the army, achieving the rank of lieutenant colonel before he returned to civilian life in 1946. In 1944, Thatcher had made his first acquaintance of the theater world in New York when he found himself on leave in the city with only ten shillings in his pocket -- he spent it sparingly and discovered that Allied servicemen, even officers, were accorded a great many perks in those days; he was also amazed and delighted when he was recognized while on his way into a play in New York by a theatergoer who was able to name virtually every movie that he'd done in England over the preceding decade. He got a firsthand look at the city's generosity and also made sure to meet a number of people associated with the New York theater scene, contacts that served him in good stead when he returned to New York in 1946, as a civilian eager to pick up his career. He starred in two plays opposite Katharine Cornell, First Born and That Lady, and portrayed Claggart in a stage adaptation of Billy Budd, but his big success was in Noel Langley and Robert Morley's Edward My Son. Thatcher had been in movies in England since 1933, in small roles, occasionally in major and important films such as Alfred Hitchcock's Young and Innocent (1937) and Michael Powell's The Spy in Black (1939); his British career had peaked with a superb performance in a small but important role in Carol Reed's The Fallen Idol (1948). After moving to the United States, however, Thatcher quickly moved up to starring and major supporting roles in Hollywood movies, beginning with Affair in Trinidad (1952). He was busy at 20th Century Fox, Universal, and Warner Bros. over the next decade, moving between their American and British units, and stood out in such hit movies as The Crimson Pirate (1952) (as the pirate Humble Bellows) and Love Is a Many-Splendored Thing (1955). Although Thatcher could play benevolent characters, his intense expression and presence and imposing physique made him more natural as a villain, and he spent his later career in an array of screen malefactors, of whom the best known was the sorcerer Sokurah in The 7th Voyage of Sinbad (1958), directed by Nathan Juran. Thatcher and Juran were close friends and the director loved to use him -- the two became a kind of double act together for a time, turning up in "The Space Trader" episode of Lost in Space, guest-starring Thatcher and directed by Juran.

Trivia: Welsh-born actor Gerald Hamer was one of a legion of British actors working in Hollywood in the 1930s and 1940s. A character player who could melt into any part he portrayed, he might be totally forgotten today except that he has the distinction of playing one of the most sinister roles in any of the Basil Rathbone/Nigel Bruce Sherlock Holmes movies, the part of Potts/Tanner/Ramsden in The Scarlet Claw. A true psychopath, with none of the suave villainy of, say, George Zucco or Henry Daniell in their portrayals of Holmes' antagonists, Potts is memorably crafty and savage in a series that usually prided itself on glib-tongued villainy. It's also a tribute to Hamer's skills as an actor that the producers saw no reason not to use him in roles in four other films in the series, as John Grayson/Alfred Pettibone in Sherlock Holmes in Washington, Kingston in Pursuit to Algiers, Major Langford in Sherlock Holmes Faces Death, and Mr. Shallcross in Terror By Night, the latter two after The Scarlet Claw. A British stage veteran from 1916, whose theatrical credits included King Henry VIII, The Taming of the Shrew, and The Admirable Chrichton, Hamer worked in Hollywood from the mid-'30s until 1951, his other thrillers include Bulldog Drummond's Bride and The Lodger, but he also slipped into more benign settings, such as the cast-of-hundreds war relief effort Forever and a Day and George Stevens' Swing Time, equally well.
