I have not yet had time to sit down and watch either film all the way through (although I'm probably going to spin Battle right after I finish this post), but I have given both discs a quick scan. Battle looks gorgeous. There are a few specks and scratches here and there, but it's a quantum improvement over the original New Concorde DVD from a decade or so ago (that print looked like it had been stored in a ditch). I would never have imagined that this low-budget Roger Corman space opera could ever look as good as it does here. For one thing, you can finally appreciate all the skill that the miniature crew put into designing and detailing the model spaceships.
The Damnation Alley transfer doesn't quite fare as well; the film was shot on very grainy 70s film stock, and all the optical effects that were added in post only degrade the image further. Still, it looks vastly better than any cable TV print I've seen, with much stronger colors and contrast - and it's in its correct 2.35:1 'scope aspect ratio.The extras look promising, too.
Look for full reviews shortly, both here and at my DVD Late Show site.
