Lows in the Mid-Eighties (1) - S3-E8
Continuity mistake: In the scene in which Will is sitting in Bobbie Adler's bathroom, talking to Jack on the telephone, the shots alternate between the bathroom and Jack's bedroom. At the beginning of their conversation, the digital clock in Jack's bedroom reads 12:07. For the next few shots, each time the audience is taken back to Jack's bedroom, the time on the clock has changed according to the actual time lapsing in the scene. However, in the middle of this sequence, the digital clock suddenly reads 12:24, where it had read 12:09 in the shot immediately preceding. Finally, in the very next shot in Jack's bedroom, the clock has gone back to "real time," with a reading of 12:10. The assumption is that the shot in the middle of this sequence had to be re-done, thus reflecting the time passage on the clock. (00:15:30 - 00:17:40)
