Morse began his career in the casting department of
Paramount Pictures, and eventually began to work closely with director
George Stevens. During World War II, Stevens was Morse's commanding officer in the
U.S. Army Signal Corps, where Morse rose to the rank of
first lieutenant. In that capacity, Morse traveled with Stevens's unit through Europe and helped capture footage of the
Battle of Normandy and other significant events of the European war. Morse reflected on these experiences through his participation in
George Stevens Jr.'s 1994 documentary,
George Stevens: D-Day to Berlin. ==Television==
