Béla Ferenc Dezső Blaskó, better known as Bela Lugosi, was a Hungarian-American actor, famous for portraying Count Dracula in the 1931 film and for his roles in various other horror films. He had been playing small parts on the stage in his native Hungary before making his first film in 1917, but had to leave the country after the failed Hungarian Communist Revolution of 1919. He had roles in several films in Weimar Germany before arriving in the United States as a seaman on a merchant ship. In 1927, he appeared as Count Dracula in a Broadway adaptation of Bram Stoker's novel. He later appeared in the classic 1931 film Dracula by Universal Pictures. Through the 1930s, he occupied an important niche in popular horror films, with their East European setting, but his Hungarian accent limited his repertoire, and he tried unsuccessfully to avoid typecasting. Meanwhile, he was often paired with Boris Karloff, who was able to demand top billing. To his frustration, Lugosi was increasingly restricted to minor parts, kept employed by the studio principally for the sake of his name on the posters. Among his pairings with Karloff, only in The Black Cat, The Raven, and Son of Frankenstein did he perform major roles again, and, even in The Raven, Karloff received top billing despite Lugosi performing the lead role. By this time, Lugosi had been receiving regular medication for sciatic neuritis, and he became addicted to morphine and methadone. This drug dependence was noted by producers, and the offers eventually dwindled down to a few parts in Ed Wood's low-budget movies, most notably Plan 9 from Outer Space.
