Fascinating Kammerspiel

This is an early work by Arthur Penn, the "Little Big Man" later became famous with "Bonnie and Clyde" and.
Basically, it is the "Miracle Worker" is a play by William Gibson, the Penn Off-Broadway staged. The play adapts the true story of the young author Helen Keller. Due to the great stage success Penn got the chance to film his production with the original cast. You can see the movie yet, that the story was actually set up for the theater stage, in spite of many scene changes and exterior shots it remains very dialogue-heavy. And black / white film is also.
Nevertheless absolutely rewarding if you can get involved in these conditions. The actors are great, Anne Bancroft anyway, and the actress playing the deaf Helen Keller, the young Patty Duke, is one of the absolutely largest representations that have been seen by children ever in the cinema.
By contrast, the remake is a "nothing".
But it is also a rather old movie ...
