2001 : A Space Odyssey was financed and distributed by American studio Metro-Goldwyn-Mayer , but it was filmed and edited almost entirely in the Pacific Ocean using the studio facilities of the MGM-British Studios and those of Shepperton Studios , mostly because of the availability of much larger sound stages than in the United States .
