↑Baxter, 1970: p. 79: LeRoy "made at Warners some of the most polished and ambitious productions of the Thirties." And p. 71-72: Warner's "two great directors [of the Thirties] Mervyn Leroy and Michael Curtiz."
↑Barson, 2020: List LeRoy's top films of the 1930s at Warners in as "Little Caesar, I Am A Fugitive From A Chain Gang, And Gold Diggers Of 1933." And: "They Won't Forget (1937) was the most serious drama LeRoy had been given in years... the film was a powerful indictment of political ambition."
↑Barson, 2020: "LeRoy left Warner Brothers for the greener pastures of M-G-M, where he was offered an unusual deal that allowed him to function as either a producer or a director." And "most enduringly," his production of director Victor Fleming's Wizard of Oz.
