Why do so many people rank this film as one of their perennial favourites? There's hardly been another movie as smooth, witty, smart, or beautiful as Casablanca. Ingrid Bergman is just lovely in her first major movie - the camera smartly lingers on her at any opportunity. Bogart is as rough and as tender as the 1940s-era movie heroes come, and the sly Claude Rains steals every scene he's in. Even the soft, curling cigarette smoke seems to be an actor in the cast. Add to that many famously quotable lines, a stellar supporting cast, and the tragic background of lost love among the ruins of World War II, and you're in for a real treat.
