Just a reminder that King Kong, which ran 104 minutes with an overture, delayed the entrance of the big ape until the 46-minute mark. Build-up, set-up. In other words, co-directors Merian C. Cooper and Ernest B. Schoedsack made the audience wait until nearly the midpoint of this not especially long film to deliver the simian thrills. The Skull Island adventure chapter lasts for roughly 38 minutes, and ends at the 84-minute mark. The New York City finale lasts exactly 20 minutes, or from the 84 and 1/2 minute mark to 104 minutes and 23 seconds.
Peter Jackson‘s absurdly bloated King Kong (’05) ran 188 minutes.
