Documentaries are a genre I favor, but even within this group, some stand out from the crowd for being especially audacious and adventurous.
In this group is "The Great Flood," a film directed by Bill Morrison, who combines newsreel and archive footage of the Mississippi River Flood of 1927 with a haunting, hypnotic score by Bill Frisell. It's been released on DVD by Icarus Films and is a knockout.
Just as good and one of my favorite docs, released by Cinema Guild, is Thom Anderson's 2-hour, 50-minute "Los Angeles Plays Itself," a completely fascinating look at the various ways the City of Angels has been used in feature films. Not to be missed.
