The Big Country
Simmons had a big success, though, in "The Big Country "(1958), directed by William Wyler. She starred in "Home Before Dark" (1958) at Warner Bros. and "This Earth Is Mine" (1959) with Rock Hudson at Universal. In the opinion of film critic Philip French, "Home Before Dark" was "perhaps her finest performance as a housewife driven into a breakdown in Mervyn LeRoy's psychodrama."
