By the time Splendor in the Grass was released in theaters, Natalie Wood had split from husband Robert Wagner, and Warren Beatty and Joan Collins had called off their engagement. Wood and Beatty started seeing each other and suddenly became one of the hottest Hollywood couples of the moment, though they would ultimately split a short time later. Elia Kazan also went on to eventually divorce his wife and marry actress Barbara Loden in 1967. The two remained married until Loden's death in 1980.

Splendor in the Grass was remade as a television movie in 1981 starring Melissa Gilbert as Deanie and Cyril O'Reilly as Bud. Ned Beatty played Bud's father Ace, Eva Marie Saint played Deanie's mother and a then-unknown Michelle Pfeiffer played Bud's troubled sister Ginny.
