One giant flaw in the Wedlock system...
I love this film, so don't get me wrong...but the prison has one gaping logic problem.
Tobolowsky explains to the inmates all about their wedlock collars, and that you won't know who your partner is so you cannot cross the blue line. Right?
Except we see multiple times that when the distance is too great, BOTH collars start to beep, warning the wearers to get closer again. So all you have to do is take a step over the blue line, see which collar starts to beep when yours does and voilĂ ! You know who your partner and you both walk on out of there. :)
