Yes shooting your feature film on an iPhone is old hat, but in 2012 nobody figured out that the Pompeywood paranormal frugalwave flick "GAIN" had been shot on a phone.
Here we are in 2016 and the truth has been revealed!
From the video description (at time of writing):
Feature film filmed on iPhone 4S, ungraded.
This version divides opinion - those who side with britmic believe no grading is necessary in order to preserve the laziness of reality.
Conversely, the final release was colour graded before Evil C would give it his approval since it was felt lazy reality was too harsh, particularly the scene in the supermarket.
