From award-winning director Phil Grabsky comes this fresh new look at arguably the world’s favourite artist – through his own words. Using letters and other private writings I, Claude Monet reveals new insight into the man who not only painted the picture that gave birth to impressionism but who was perhaps the most influential and successful painter of the 19th and early 20th centuries.
