Trailer
A collector’s booklet featuring a new essay on the film by film writer Rich Johnson, and a new piece by critic Richard Combs about the Western films of King Vidor
This should better the German and Kino BDs by being on a BD-50, and the audio commentary plus video piece make it a more complete release, too. I've not seen it before but I liked Vidor's other western, Duel in the Sun.
The Kino disc is pretty competently encoded (the Explosive Media disc is their usual garbage). Personally, I don't expect the Eureka disc to be a huge difference since there's not really much to pull/gain from the dated HD master.
