Studio-era Expenditures

I'm still exploring the "snapshot" dimensions of the 1947 project. For instance, looking at budgets from 1947 films allows me see both product differentiation (different genres and prestige levels got different budget allocations) and system similarity (studio filmmaking systematically minimized expenses that later would explode; technological constraints required expenditures that would later be minimized). To take the example of RKO, I chose three films and charted out exactly where the budget money went:

These show the top expenditures, by category - minor categories, of course, add up to a substantial portion, between a quarter and a third of costs. Note that these are relative budget comparisons, not absolute. The direct-cost figures for the budgets are as follows:

Sinbad the Sailor $1,911,138.36
Mourning Becomes Electra $1,800,320.86
A Likely Story $475,545.01

For Sinbad (a Technicolor film), film and laboratory costs run 3 percent, where they do not rank in the top expenditures for the other two, B&W features. Here are the actual film/lab costs:
Sinbad $52,113.86
Mourning $20,237.10
Likely $9,323.23

Mourning has twice the running length of A Likely Story and I would not be surprised - given its prestige, independent production and long take aesthetic - if it had a higher shooting ratio, as well.

But perhaps the biggest lesson is how much lighting costs in studio filmmaking. I have no idea how much it costs now to light a film, but the relative portion of lighting costs must be miniscule in comparison.

By the way, an RKO B-Western, say Under the Tonto Rim, cost only $143,855 in direct cost.
