From an interview with Mike Slack at flashfilm.com:

“I keep a long mental list of things that I try (and often fail) to avoid shooting. That list includes: funny-looking bushes; chain link fences; street signs; arrows of any kind; empty parking lots; painted brick walls; weeds; stairs; shadows; doors; rain gutters; tools; words; hats; the backs of people’s heads; trash; trash cans; empty roads; plush toys; food; loading docks; telephones; cracked sidewalks; shopping carts; manhole covers; water towers; inanimate objects that resemble sex organs; airplanes; shoes; telephone wires; water puddles; clouds; stray dogs; ugly office buildings; brightly colored flowers; the ocean; empty hotel rooms; long hotel corridors; birds; air conditioners; fire hydrants; curtains; framed paintings; crashed cars; cell phone transmitters; and sofa cushions.”

Fuck. I am so busted.
