Francis Ford Coppola Directs 'John Grisham's the Rainmaker'

I've found it a really generous and energizing "workshop" documentary on the work of a director with actors. You get a glimpse of how even "huge" actors like Jon Voigt or Danny DeVito can benefit from images and an atmosphere to be able to really "play". As Francis F.Coppola said it it's an actor department in the film and the documentary shows you how it is run. You can get how improv is done and help the acting of the scene. I've found it a precious document because it gives you a feeling of all the actors insecurities and at the same time how to handle them as a director. This is quite surprising to have opened the process of filmmaking to such an extent. I actually see it as the actual working version of "Day by night" of François Truffaut, how you actually need to form "une troupe" with actors (the exercise of the imaginary ball !) to give them confidence and love ! Really great.
