Holy Shiii...! I finally unlocked the secret menu on the T2 DVD!!!
My regular DVD player doesn't have numbers so I was dismayed that I couldn't do the secret menu unlock trick....but then I dusted off my old PS3 and popped in the disc. At the screen where you see the exoskeleton with one eye glowing, I entered the code (82997), which is the date for Judgement Day and the second eye lit up, the words "The Future is Not Set" appeared on the right, and the Theatrical Version option changed to Extended Special Edition! Pics included for anyone curious about this feature.
Some context: I have only ever seen the original theatrical release and never seen any of the alternate versions so I'm super stoked by this! Just got to the point when Sarah and John Connor perform brain surgery on Arnold. I feel like a kid watching this movie again!
