What is Billy Connolly's net worth? Billy Connolly, the Scottish comedian, has a net worth of $20 million. In addition to his net worth, he's earned the respect of many of his peers and comedy fans for his unique style, which combines a folky and casual presentation with often hard-hitting social commentary. Connolly began his career in show business not as a comedian, but as a folk singer in Scotland in the 1960s. After working as a folk musician both in a group and as a solo performer, Connolly's humorous introductions to his folk songs began to get longer and longer in duration. It was through this slow, gradual change that Connolly eventually transitioned into being a comedian. Connolly quickly became a big comedy star in his native Scotland, although it took him a bit longer to find an audience in the United States. It wasn't until 1990 that Connolly had his big break in the States, thanks to fellow comedian Whoopi Goldberg. The HBO special that introduced Connolly to many people in America was called Whoopi Goldberg and Billy Connolly in Performance, and it launched Connolly on the path to American stardom that he still enjoys today. He is arguably best known among younger fans for his role as Il Duce, the silent killer in the film The Boondock Saints.
