Answer to the op's question: no.
delicious food to keep everyone energized, happy to be there, and to possibly compensate for a shooting schedule that will likely be very rushed...
...the first "luxury" I would want is a talented DP with a better mind for creating a beautiful image in-camera than I. The second is an audio expert, with a better mind for capturing clean sound...
But that's no surprise coming from me, is it?
I agree with everyting that has been replied. However
Check out Shane Carruth's films "Primer" and "Upstream Color".
He made the former doing almost everything himself (writing, directing, acting, editing, being the DP, operating cameras for some shots, sound design composing, etc) and on a budget of $7000/$8000 (apparently he managed to negotiate cheaper camera rentals by explaining that El Mariachi had the same budget, and therefore, it was impossible for cameras to be this expensive). It is not an amazing film (it is very good), but for the way he made it, it's incredible.
Upstream Color had a more significant crew, but he still took on a huge number of roles, and it is an incredible film (he also had a real budget for it).
