Not as great as Resnais' earlier documentaries, perhaps, but very very rare! Gershwin fans will love it for sure, and for Resnais admirers it's a must too. Resnais relies more on talking heads and traditional techniques of television, differntiating this storngly from the likes of Night and Fog. but the interviews are enmeshed in a graphic style that makes the film into something like an illustrated booklet. Unusual and charming.
