I saw it that Monday (the 17th) in a regular theater, then I saw it in 70mm IMAX that Thursday night (the 20th). Guess I missed my anniversary.
I did however see it three more times in theater. Once as an impromptu early-bird showing when I first arrived into Reno from a night drive, then twice more in 70mm IMAX: once a couple weeks later with my sister, her boyfriend and her other friend; another time during the Oscar season re-release. I'll have to make sure I catch one of those anniversaries for sure!
