John August also talks about it in episode 74 of his podcast with Craig Mazin called Scriptnotes: http://johnaugust.com/2013/three-hole-punchdrunk

Although you need to pay to access archived podcasts they have all of them transcribed: http://johnaugust.com/2013/scriptnotes-ep-74-three-hole-punc...

I highly recommend the podcast to anyone even remotely interested in the movie industry. I've been listening for around 6 months now and can't stop.
