In December 1932 – January 1933, the actors were called back to film a number of optical effects shots which were mostly rear-screen projections. Technical problems inherent in the process made filming difficult and time-consuming. Wray spent most of a twenty-two hour period sitting in a fake tree to witness the battle between Kong and a "Tyrannosaurus". She was sore for days after. Many of the scenes featuring Wray in the articulated hand were filmed at this time. In December, Cooper re-shot the scene of the female New Yorker falling to her death. Stunt doubles were filmed for the water scenes depicting Driscoll and Ann escaping from Kong. A portion of the jungle set was reconstructed to film Denham snagging his sleeve on a branch during the pursuit scene. Originally, Denham ducked behind a bush to escape danger, but this was later considered cowardly and the scene was re shot. The final scene was originally staged on the top of the Empire State Building, but Cooper was dissatisfied and re shot the scene with Kong lying dead in the street with the crowd gathered about him. The final negative cost of King Kong was $672,254.75, $270,000 more than the original projected budget.
