This might very well be the finest, most exciting, most intricate screenplay I have ever seen on film.  Sure it is an ADAPTED screenplay, but the verbal fencing match that Richard Burton and Elizabeth Taylor engage in is simply mesmerizing.  Watching them go at each other and sucking in the young couple into their despair is nothing short of masterful entertainment.  Mike Nichols directs, and the entire film is so expertly executed that you could swear it was real, and done in one take.  What a perfect film.  I loved it!!!
