I watched the 1967 film "Bonnie and Clyde" last night. The movie was enjoyable enough, but it always bothers me when period films aren't authentic to the time they're portraying. I just don't take it as seriously.
The producers seemed to have had enough money to put into the set, the cars, and even the clothes. When it came to doing the hair and make-up though, it looked like they just couldn't be bothered. So what did they say, "Hey guys, we just spent all this time and money making the whole town look like the early 30's, but don't worry about hair and make-up! Just do it modern 1960's!"
This is most recognisable on Faye Dunaway's character Bonnie. I have posted a photo of the real "Bonnie". Even if they didn't want Faye to look exactly like Bonnie, they could have at least given her a 1930's look. The 30's were known for short hair, finger waves and thin eye-brows, but there you have Faye with her very 60's hair and heavy liquid eyeliner.
