The bit at 1:21 is officially the sweetest thing ever.
i wish there were more blooper reels available to the public. the BFI in london have still quite a stack of unseen material. so kevin brownlow could easily make another documentary. (and the more you see of these, the more you are amazed that he didn't break more bones in his body!)
...or that footage could be added as extras on some of the upcoming Criterion releases (I know those aren't available where you are!)
yeah, drive another nail through my heart, why don't you!?! ;)
