Was the Planet of the Apes the 1960's movie script or was it a twilight zone episode?

I read the book by Pierre Boulle many years ago, and Serling had no part in that effort.

I was also a big fan of Rod Serling, and some months ago I posted some information about him was was easily obtainable from diverse internet sources.

1960s movie script.

True but Serling's script actually improved things. Boulle set the ape society in a futuristic setting. Serling changed that so the apes advanced only to the technological level of the 19th century. It worked beautifully on the big screen that way.
