GOODFELLAS
When Henry Hill takes Karen to the Copacabana.
"["Then He Kissed Me," performed by The Crystals.] As they make their way into the famed Copacabana club, the camera follows behind them - it is a three minute, non-stop, unedited take/tracking shot with mobster-in-training Henry greasing the portals at each step with $20 bills as they enter the circuitous world. The camera hovers just over their shoulders as they arrive at the front of the club, have their car attended by a valet, bypass the long line into the entrance by taking a side entryway, wind through hallways and then into the bustling kitchen area with cooks and helpers, pass other patrons waiting inside, and are set-up by the Copa Captain at a prime, front-row table (hastily resurrected out of nowhere and set up especially for them at ringside).
Karen is naively wide-eyed and impressed by his endless cash supply, his familiarity with everyone and his innumerable friends (one group sends over champagne), his power, and his slick waggering style: "You gave them twenty dollars each."
Karen: What do you do?
Henry: I'm in construction.
Karen: (She feels the softness of his hands) They don't feel like you're in construction.
Henry: Ah, I'm a union delegate. "
A personal favourite...really conveys the feeling of being a 'minor deiity' to this young man, which I don't think could of been achieved by lots of editing.
Definitely adds to the film, and is not just shoved in on a whim.
[Edit : damn, just saw Rath's post...yet, glad I'm not alone.]
