Shockingly little: the math is unappealing. The exhibitor automatically keeps 50%, so that leaves $6 out of $12. That goes to the distributor. The distributor will charge a distribution fee. Call it 30%. Sometimes it's less and sometimes it's more. Thirty per cent of $6 is $1.80. That leaves $4.20. Of that $4.20, then, the distributor uses some, because next comes amortizing his marketing costs, whatever they are. What's left after the marketing costs are paid for comes to the producer, who in turn shares that with his investors and with his talent, with the actors and the director, all of whom participate.
