Michael Keaton wears a pair of Randolph Engineering Aviator sunglasses in the movie American Assassin (2017). The sunglasses can be recognized by their typical bayonet temples, that are designed to fit comfortably under headgear. The glasses can be clearly seen in the film and on the movie poster.

The glasses can be seen in many films, for example Tom Cruise wears the same sunglasses in the recent movie American Made and in Oblivion.

Buy Randolph Aviator sunglasses online at the official Randolph website, on Amazon.com or find them on eBay. 

Randolph Engineering began as the American dream - two immigrants that started a company making machines to build the parts for other metal eyewear companies. As the others started moving overseas, Randolph started their own sunglass brand and remains the last of the metal eyewear companies made in the United States. Having had a contract supplying the standard-issue glasses to the military since 1982, Randolph is known for their exceptional quality and attention to detail.

This hand assembled, US brand is often spotted in films and tv series, see more Randolph Engineering sightings here.
