20 Recent Movie Cameos NOBODY Saw Coming

10. Trent Reznor & Atticus Ross - Tron: Ares

Here's a pair of cameos you literally couldn't see coming considering that the folk involved were concealed beneath helmets the entire time.

Tron: Ares' musical score was of course provided by Nine Inch Nails - Trent Reznor and Atticus Ross to be precise - and the duo actually also have fleeting cameos during one of the film's later airborne action sequences.

Reznor and Ross suited up to play F-35 pilots who are taken out by light drones during the high-wire climax. 

Though neither Ross nor Reznor show their faces or even speak in the film, behind-the-scenes images have shown the pair suited up without their helmets.

Considering that Reznor would be an immediate distraction if he appeared in the film sans-helmet, it was probably for the best that he's never actually recognisably visible on screen. 

Ross probably could've gotten away with it, though, given that he's the more low-key member of the group.
