Surely the best loved of all the Hollywood classics and certainly one of the favourites of all time, "Casablanca" had everything going for it. Bogart is at his enigmatic best playing the anti-hero for all he's worth, Bergman is beautiful and there are some great performances from the likes of Claude Rains and Sydney Greenstreet in the supporting cast. Even now, you only have to hear the opening bars of 'As Time Goes By' by Herme Hupfeld and you are immediately transported to exotic Casablanca - which was in fact the back lot of the Warner Brothers studio. As to Casablanca's famous lines, a sure sign of a picture's cult status, the usually misquoted closing line is 'Louie,I think this is the beginning of a beautiful friendship' (a last minute dub-in), while 'Play it again, Sam' comes from the Marx Brothers' "A Night in Casablanca"
