Let's go through them one by one.
Michael Chekhov was a Russian actor and director who studied under the legendary acting teacher Stanislavski; he was also the nephew of the playwright Anton Chekhov. As an acting teacher, his work influenced Marilyn Monroe, Elia Kazan, Yul Brynner, Clint Eastwood, Johnny Depp, and more. Spellbound was his fourth Hollywood film, having come to America when "tensions" broke out in Europe. He plays Dr. Alexander Brulov, an old mentor of Ingrid Bergman’s heroine, who provides a safe haven and professional advice to help her.
John Dall was a young American stage actor who starred in both the touring and Broadway productions of The Eve of St. Mark, a performance that earned him a screen test with Warner Bros, which led to his film debut, The Corn is Green. He plays Morgan Evans, a young Welsh miner who seems consigned to a life of work and drink until he starts taking classes with the new schoolteacher Miss Moffat, who sees in him a preternatural gift for writing.
James Dunn was a born-and-bred Manhattanite who, as a child, cut classes to go to the movies; as an adult, he joined theatrical troupes and eventually landed the lead in
Sweet Adeline on Broadway, which led to his contract with Fox. He made his debut as the leading man in Frank Borzage's
Bad Girl, which was nominated for
Best Picture and
won Best Director and
Best Adaptation. Despite this and a trio of hits with Shirley Temple, his star waned as he sank deeper into alcoholism.
A Tree Grows in Brooklyn was his comeback film, playing the loving patriarch of an impoverished family, a struggling actor who drinks too much. He won the Academy Award.
A boxer, a steelworker, a writer, a lyricist, and an actor, Robert Mitchum had already established himself with 25 films between 1943 and 1944, including Cry 'Havoc' (uncredited), When Strangers Marry (as Bob), and Thirty Seconds Over Tokyo. Loaned by RKO to Lester Cowan, he was cast as Captain Bill Walker, a character inspired by Captain Henry T. Waskow, the subject of one of war correspondent Ernie Pyle’s more famous columns. It and many others were adapted to make up the Story of GI Joe.
J. Carrol Naish was the definition of a character actor. Despite his purely Irish heritage, his dark, swarthy looks saw him cast as every ethnicity except Irish - Italians, Mexicans, Native Americans, Chinese, Arabs - which he portrayed in supporting parts and cameos, credited and uncredited, in a prolific career that spanned over 40 years and over 128 films! In A Medal for Benny, he plays a Paisano - "of mixed Indian and Spanish Blood" - whose ne'erdowell son is awarded a posthumous medal of bravery.
