After the scene with Paolo Rocchi, when he sniffs some "cocaine", he forgot to throw away the small plastic bag with the faked drug powder. His mother cared about the washing - and found it. Paolo needed to eat five grams of cornflour for proving her it was no drugs.
One of the actors broke one of his toes and his thumb during the shooting period (not on the set). If you pay attention to some movements you can notice who it was.
Giorgio is the only character who hadn't been dubbed by the actor himself. He's living too far away from the recording studio and the job needed to be done pretty fast.
The whole movie has been shot with a single small camcorder with a fixed lens with a cost of approx. 1,500$. Shooting endured 10 days and the ratio was of 3:1. The lighting park consisted of 3 tungsten soft heads and 3 spots and 1 HMI daylight spot, of a total power consumption of about 2.2kW.
It was pretty hard to find a location, i.e: an abandoned house in the countryside, with water and electricity available. That place in Bellocchi di Fano (PU), Italy, was perfect. Every single spider's web, every insect and all the dust are real.
