Like I said in another post recently, I can at least understand WB not putting out the original version(s) of THX, but that's not how I look at Graffiti. It's had one of the biggest gross-to-budget ratios of all time. It's in the national film registry (just like Star Wars). It's just ironic how the only cgi tinkering done to the film is that one single shot.
I still say, given its relatively short running time, WB could've easily fit both cuts of THX on a dual-layer blu-ray. Actually, I'll be curious to see if next month's release ends up being a single-layer disc.
