[Carole Lombard engineered for herself] one of the finest, fattest new contracts in Hollywood–Paramount to pay her $150,000 per picture, for three pictures a year; Carole to have full and final say on all production details! And besides that, she’s to have the right to make one picture away from Paramount each year–when and what she pleases. Oh, I say, do you hear London calling?
