This gives the copyright owner the freedom and right to make the best deal possible at that time. The producer also finalizes his own production contract with the studio/network/finance company. The project cannot move forward unless the copyright owner and the producer each enter into separate agreements. This protects both the copyright owner and the producer and allows both to negotiate with the studio/network/funding unit in order to reach an agreement satisfactory to each. The main advantage for the copyright owner is that a literary option/sale agreement sets the sale price and cannot be changed without a modification agreement, and the producer who has the optional literary property can actually earn more than the copyright owner when selling to a studio; network; or another financing unit. . . .
