None of the scenes were rehearsed before filming. The filmmakers just started shooting and then used the stuff that they liked and changed the parts that didn't work.
The film came about because the director, Adrian Murray, lived in a house with the star, Aaron Keogh, as well as with some of the other cast members. Based on the things he observed living there, he thought he could make a good movie out of it.
Most of the dialogue was improvised.
Some of the only bits of scripted dialogue were Dean Tardioli's lines, as his character had long, detailed monologues.
Filmed mostly on weekends with a shoestring budget.
