The Thin Man was a detective novel Dashiell Hammett wrote which spawned six movies based around the characters of Nick & Nora Charles. Nick is a ex-New York detective who is a retired private eye. His wife is a bored, wealthy California socialite who loves the mysteries the two of them subsequently end up stumbling into and encourages Nick to solve. They have some of the best banter in film history and they love, love, LOVE to drink. Not only do they make it look good, alcohol is never vilified as a killer, but a perfectly good hobby (I couldn't agree more). Put your highballs together for some classy partaking.
On a topical side note, Johnny Depp is working to redevelop a new version of The Thin Man.
