One of the things that have bothered me the most in this film, is when in the day the scenes are supposed to take place.
For example: from Deck's first meeting with Bryant until going home to find Rachael waiting for him, how much time has passed? The whole night? It seems that Deckard was eating chinese food at night, but then when summoned to Tyrell, he asks him to close the windows, since it's "too bright". Is it morning by then? Then again, later in the film, Roy and Pris are having breakfast with Sebastian, but then Sebastian and Roy go to meet Tyrell and after killing him, Roy sees stars from the elevator.
So, basically: what the heck is going on with the time in BR?
