I have watched the new standard DVD and Blu-ray of Rio Grande from Olive Films.
This looks to be a new transfer and it looks very nice. Comparing the new DVD to the old one from Artisan, the image looks a bit more stable with a bit more detail and a little brighter. However, there's no need to rush out to replace your old DVD, it still looks pretty good too. Also, the Artisan DVD had a commentary by Maureen O'Hara which is not on the new DVD, so that's another reason to hang onto the old one. The "Making of Rio Grande" featurette with Leonard Maltin (and interviews with Michael Wayne, Harry Carey, Jr. and Ben Johnson) on the old DVD is included on the new one, so that's good -- the but new DVD's menu lists it as "The Making of High Noon." Oops!
However, both old and new DVDs are left in the dust by the new Blu-ray, which is really beautiful. Just amazing clarity and detail. You feel like the actors are right there in your living room, and you can almost feel the texture of the fabric of their shirts, the dust, the leather of the saddles.
It's pretty obvious that no extra digital clean-up was done on this transfer; it has a number of flecks and lines showing print damage, but this is minor and won't interfere with your enjoyment of the film.
To sum up: The new Blu-ray is the optimal way now to see Rio Grande at home. But if you don't have a Blu-ray player, then either one of the standard DVDs is OK.
And now the latest addition to my Ben Johnson webpage (http:benjohnsonscreencaps.shutterfly.com). Enjoy! :)
