In the movie Black Hawk Down, Eric Bana (as Sergeant First Class Norm "Hoot" Hooten) wears a pair of Oakley Juliet sunglasses.

Oakley Juliet sunglasses have an adjustable frame that includes temple shocks and interchangeable nosebombs.
Juliet sunglasses feature Oakley Hydrophobic™, a permanent lens coating that prevents rain and sweat from building up on the lens. It also repels skin oils and other contaminates, so the lens is smudge resistant and easy to keep clean. It even eliminates static electricity, so dirt and dust particles won’t cling.

Trivia (source IMDB): In the film the brand name Oakley is mentioned when Pilla (Danny Hoch) is impersonating Captain Steele (Jason Isaacs), saying "Delta don't wear Oakley".
The appearance of Juliet sunglasses is chronologically incorrect, because the events depicted in the film took place in 1993 and Oakley did not start marketing these specific sunglasses until 1999.

These famous and popular Oakley sunglasses are still available, buy and customize your pair on Oakley.com.
