Movie reel

Trying to find imagery which I can use as a background image for this poster... I want something which clearly says filmmaker and not just promoting a film.

Filmmaking (often referred to in an academic context as film production) is the process of making a film, from an initial story, idea, or commission, through scriptwriting, casting, shooting, editing, and screening the finished product before an audience that may result in a theatrical release or television program. 

I though an image of some movie reel would be good but surprisingly, this was hard to come across...
