Truth is, we did it because we had left over stock. Ha! But we are planning to do our feature in 16mm - but with more stock in hand. We had one chance to do the cover shot from beginning to end - 15 minutes beginning to end- non stop. Damn near died when I got the word! But we did it... but never again. I'll pay for the stock myself if I have to. Dang! We do love the film finished product.
