In the 1930s, there were several big budget science fiction films, notably "Just Imagine" (1930), "King Kong" (1933), "Things to Come" (1936), and "Lost Horizon" (1937). Starting in 1936, a number of science fiction comic strips were adapted as serials, notably "Flash Gordon" and "Buck Rogers", both starring Buster Crabbe. These serials, and the comic strips they were based on, were very popular with the general public. Other notable science fiction films of the 1930s include "Frankenstein" (1931), "Bride of Frankenstein" (1935), "Doctor X" (1932), "Dr. Jekyll and Mr. Hyde" (1931), "F.P.1" (1932), "Island of Lost Souls" (1932), "Deluge" (1933), "The Invisible Man" (1933), "Master of the World" (1934), "Mad Love" (1935), "Trans-Atlantic Tunnel" (1935), "The Devil-Doll" (1936), "The Invisible Ray" (1936), "The Man Who Changed His Mind" (1936), "The Walking Dead" (1936), "Non-Stop New York" (1937), and "The Return of Doctor X" (1939). The 1940s brought us "Before I Hang" (1940), "Black Friday" (1940), "Dr. Cyclops" (1940), "The Devil Commands" (1941), "Dr. Jekyll and Mr. Hyde" (1941), "Man Made Monster" (1941), "It Happened Tomorrow" (1944), "It Happens Every Spring" (1949), and "The Perfect Woman" (1949).
