William "Billy" Connolly, CBE is a Scottish comedian, musician, presenter and actor.
He is sometimes known, especially in his native Scotland, by the nickname "The Big Yin".
His first trade, in the early 1960s, was as a welder in the Glasgow shipyards, but he gave it up towards the end of the decade to pursue a career as a folk singer in The Humblebums and subsequently as a soloist.
In the early 1970s, he made the transition from folk-singer with a comedic persona to fully-fledged comedian.
Connolly is also an actor and has appeared in such films as Water; Indecent Proposal; Muppet Treasure Island; Mrs.
Brown; The Boondock Saints; The Man Who Sued God; The Last Samurai; Timeline; Lemony Snicket's A Series of Unfortunate Events; Garfield: A Tail of Two Kitties; Open Season; The X-Files: I Want to Believe; Open Season 2; Brave and The Hobbit: The Battle of the Five Armies.
Connolly reprised his role as Noah "Il Duce" MacManus in The Boondock Saints II: All Saints Day.
