For the Warners, Epstein and his brother collaborated on Raoul Walsh's "The Strawberry Blonde" (1941), Elliott Nugent's "The Male Animal" (1942, based on the Nugent-James Thurber play) and Frank Capra's adaptation of Joseph Kesselring's play "Arsenic and Old Lace" (1944). The pair also worked with Mark Robson ("My Foolish Heart" 1950, based on a J D Salinger story), George Cukor ("Born Yesterday" 1950, uncredited from the Garson Kanin play) and Richard Brooks, ("The Last Time I Saw Paris" 1954, based on an F Scott Fitzgerald story, and "The Brothers Karamazov" 1958, adapted from the novel by Fyodor Dostoyevski), among other directors. Beginning with Philip Leacock's "Take a Giant Step" (1958), which he also produced, Epstein wrote alone for the most part, scripting Joshua Logan's "Tall Story" (1960) and "Fanny" (1961), Norman Jewison's "Send Me No Flowers" (1964) and Robert Ellis Miller's directorial debut, "Any Wednesday" (1966), before earning his third Oscar nomination for Martin Ritt's "Pete 'n' Tillie" (1972, also co-producer). His collaboration on Sam Peckinpaugh's "Cross of Iron" (1977) preceded a final success with his last screenplay (to date) for Miller's "Reuben, Reuben" (1983), which earned him a fourth Oscar nomination.
