Interesting fact:

You may think that certain aspects of spy films are ridiculous, particularly when it comes to disguises – but they’ve been working for centuries! Take Karl Schulmeister, a spy for none other than Napoleon Bonaparte. One instance saw him fleeing perusing Austrian soldiers who chased him into a boarding house. Upon arriving inside they were greeted by a barber, who said that the spy had run upstairs. After they’d left, Karl ditched his barber disguise and fled the scene. Some serious ‘Catch Me if You Can’ vibes right there.
