If you only ever watch one classic movie (those filmed in black and white, before you were born), you won’t go wrong if you choose All About Eve. Amazing script, great performances and witty dialogue… it really is one of the best movies ever made.
Interesting interview with Paul Verhoeven (from 2002). I really enjoy the unique view of the world he creates in his movies (I even found Showgirls not that bad!), and his tasteful use of sarcasm, humor, sex and violence.
