Since You Went Away is a 1944 American film directed by John Cromwell for Selznick International Pictures and distributed by United Artists. It is an epic about the American home front during World War II which was adapted and produced by David O. Selznick from the 1943 novel Since You Went Away: Letters to a Soldier from His Wife by Margaret Buell Wilder. The music score was by Max Steiner and the cinematography by Stanley Cortez, Lee Garmes, George Barnes (uncredited) and Robert Bruce (uncredited).
The movie is set in a mid-sized American town, where people with loved ones in the armed forces try to cope with their changed circumstances and make their own contributions to the war effort. The town is near a military base, and some of the characters are troops serving Stateside.
Though famously sentimental in places, Since You Went Away is somber at times about the effects of war on ordinary people. Some characters on the homefront are dealing with grief, loneliness or fear for the future. Wounded and disabled troops are shown in the hospital scenes.
The farewell scene between Jones and Walker at the railway station was parodied in the 1980 film Airplane!.
