Peter Brook, one of the greatest theatrical directors of all time, directs King Lear, arguably the greatest play of all time, by surely the greatest playwright of all time. But those credentials alone are not always enough to guarantee that a film made with them in combination will succeed. In this case, however, the results are brilliant. Spare, harsh, quivering with life, this film is Beckettian in its imagery, and innovative in its photography, unified in its tone, and demonically vital in its acting. I venture to say that the other reviewer who thought that the camera moved about too quickly is probably jostled by bumpy train rides. This film is true to the essence of Lear as I perceive it. See for yourself, and go see some theater sometime soon, as well.
Another note, I've been searching for a copy of this film in America for eight years. Thanks Amazon UK!
