Cooper led movie production for
RKO Radio Pictures before and after
World War II. He frequently collaborated with
Ernest B. Schoedsack.
Cooper started his film career with
documentaries for
Paramount Pictures such as
Grass (
1925) and
Chang (
1927), which combined real footage with staged sequences. In
Chang , he used this technique to create a memorable finale featuring an
elephant stampede. His movie
Two Feathers was filmed among the fighting tribes of the Sudan.
Throughout his career, Cooper was a proponent of technical innovation. The film
King Kong, which he co-wrote, co-directed, and appeared in, was a breakthrough in this regard. Additionally, Cooper helped pave the way for such ground-breaking technologies as
Technicolor and the widescreen process
Cinerama.
Cooper was a good friend and frequent collaborator with noted Western director
John Ford. In 1947, they formed Argosy Productions and produced such notable films as
Wagon Master (
1950),
Rio Grande (
1950),
The Quiet Man (
1952), and
The Searchers (
1956). He was nominated for an
Academy Award for producing
The Quiet Man in 1952, but lost to
Cecil B. DeMille's
The Greatest Show on Earth. Cooper did however receive an Honorary Oscar that same year.
Cooper has a star on the
Hollywood Walk of Fame (his name is misspelled "Meriam C. Cooper").
