Did anyone notice the pitch of the opening theme is a liiiiiiiiiiittle bit above the original keynote? Is it possible that the video got fast forward 0.0001x and the voices got 1/8 pitch higher than the original? That's why it did not reach 3.5+ hrs...? I went to compare the differences between this opening theme with my own mp3, and another one with the one on Youtube. And it IS slighty a pitch higher. It's almost unnoticeable.
But then I saw the 358/2 Days movie in Japanese release and its time span is also 2 hrs 50 minutes excluding the credits, just the same as this video (including the comparing of the opening theme of the JP and US version, although the opening song for the JP is muted, I only caught a few seconds of the beginning of the song, with the result that the US vers is a pitch higher.). So, originally, it WAS supposed to be a 2 hrs and 50 min movie. Point taken. Case closed. Lol XD
