Very true. 2 discs should be adequate for this.The films are barely over an hour, black and White and no extras or possibly a 30 minute documentary. 2 discs is plenty. There wouldn't be any noticeable difference with 3 discs. This is no different than a 3 hour movie on 1 disc. Many 3 hour movies in color and with a few extras get 1 disc and look great these discs will use far less space than that.
