I like long, complicated takes with complex choreography, such as the 8 minute take in The Royal Tennenbaums
; Donnie Darko
, in perhaps the most stylistically ambitious moment, features a long, I believe steadicam shot, from the interior hallway of Donnie's private school to the outside (there may be a cut hidden in the transition from inside to outside) that features almost all of the characters central to the movie. What makes this shot even more interesting, is that Kelly changes the film-speed throughout the sequence (for example, it goes fast to normal, to fast again, and so on); joker is this done in camera during the shooting, or is it done in post-production? I'd imagine that if it is done during the shooting, it makes choreographing the action that much more difficult, making the shot even more impressive.
