I've just binge watched Homeland Series 1, which was made about 26 years ago and other than buttons on their phones, and maybe the cut of Carrie's trousers it looked to me like it could have been made today (obviously the global political situation has evolved).
It got me thinking that if you were watching something in 1980 that was made in 1964, or something in 2000 from 1984, it would be clearly dated from the clothes, hairstyles, interiors, cars, etc.
So, my question is - have these things stopped changing, or am I so old and culturally unaware that I am not noticing? Would a 20 year old watching Homelands think they were watching a period piece?
