The Kubrick estate has actually said his last 3 films (The Shining, Full Metla Jacket and Eyes wide Shut) were made with the TV frame in mind and cropped for theaters. The current DVDs reflect that. 2001 ASO however is in widescreen of course.
Beat me by 27 seconds!
Full Metal Jacket in PAS is a POS. I've seen both, and while I did not suffer an aneurysm watching the PAS version, I sure WANTED one.
That is true of the Back to the future movies as well. In fact, I have a copy of My Bodyguard that has both full screen and letterboxed versions on opposite sides. And yes, the letterboxed version is nothing more than the "full screen" version with the top and bottom covered.
You can sometimes spot these types movies when watching the "full screen" version when you see an obvious microphone, etc. in the area that was blacked out for letterboxing and theaters.
