Time constraints forced Creelman to temporarily drop "The Eighth Wonder" and devote his time to the "Game" script. RKO staff writer Horace McCoy was called in to work with Cooper, and it was he who introduced the island natives, a giant wall, and the sacrificial maidens into the plot. Leon Gordon also contributed to the screenplay in a minimal capacity; both he and McCoy went uncredited in the completed film. When Creelman returned to the script full-time, he hated McCoy's "mythic elements", believing the script already had too many over-the-top concepts, but Cooper insisted on keeping them in. RKO head Selznick and his executives wanted Kong introduced earlier in the film (believing the audience would grow bored waiting for his appearance), but Cooper persuaded them that a suspenseful build-up would make Kong's entrance all the more exciting.
