Everything about this production was odd. Story line was so-so. Acting was poor.
It's Cold War 1963. Why would anyone use LED overhead lighting?
Fluorescent flickering lighting should have been used.
Touch tone was invented in 1963, however the keypad that was used was more of the late 70's to mid 80's era. The women's dresses were all wrong, the syntax of vocabulary was incorrect for that era.
To the directors / producers: Make it believable!
