Guadalcanal Diary was shot from May 14 to late July, 1943, mostly on location at Camp Pendleton, near Oceanside, California. Many of the Marines stationed there were filmed while on maneuvers and a substantial number appeared in the picture in small speaking parts or as extras. The picture marked the screen debuts of stage actor Robert Rose and Richard Jaeckel, who was a studio messenger boy when he was cast in the production.
