On our New York shoot back in early October, my college pal (and fellow screenwriter) Kevin Brodie came in from Conneticut to work as script supervisor and PA -- basically to see what its like on an indie film set. Despite the frantic pace and often touch-and-go moments, Kev maintained a calmness and professionalism through-out (it probably helps that he's a high school teacher and used to working with maturity-challenged groups).
Kevin wrote up an article about his experiences working on the IWW crew on his blog and described what it was like as a non-Muslim white guy guarding the door of a mostly-immigrant mosque in Manhattan. Read it here.
