Only a select few actors become international stars in their time, but none had as unique a career as Charlie Chaplin. Chaplin was the first true film star, and he managed to do so even when films were still silent. He has been honored with too many awards to count, and the fact that his name remains instantly recognizable nearly a century after his first film is a testament to his influence. In the 1920s, the burgeoning movie industry was starting to come into its own, and alongside actor and director Charlie Chaplin, Buster Keaton was at the peak of Hollywood. It's no surprise that Keaton was so effective in silent films, because he had been practicing comedy in his family's vaudeville acts as "The Little Boy Who Can't Be Damaged", becoming a popular performer by the age of 5. Indeed, his physical form of comedy, which initially involved having his father throwing him around the stage, translated well onto the screen, and some of his slapstick and other comic gags remain legendary even today. Everything about Rudolph Valentino, from his body to the characters he played, was exotic. His career may have been abbreviated by his premature death at the age of 31, but Valentino popularized the (somewhat racist) stereotype of the "Latin lover" in Hollywood, and even his name was markedly more out of the ordinary than those of other actors. Of all the great movie stars, there may be none more enigmatic than Greta Garbo, who remains internationally famous despite the fact her life and career raise more questions than answers. How did a Swedish actress with very little film acting experience in her native land arrive in the United States and achieve instant stardom? Most actresses had to wait years before they were offered starring roles in major films, yet Garbo was ushered to the front of the line and perched atop the MGM pantheon at a time in which it was the studio par excellence.
