Lawrence Konner is an American screenwriter who co-wrote the script for the 2001 movie Planet of the Apes, in collaboration with his long-term writing partner Mark Rosenthal. Konner began as a television writer, writing for Little House on the Prairie, Family and Remington Steele. He and Rosenthal first worked together on the motion picture The Legend of Billie Jean, followed by mainstream films The Jewel of the Nile, Superman IV: The Quest for Peace, Star Trek VI: The Undiscovered Country, The Beverly Hillbillies, Mercury Rising, and the remake of Mighty Joe Young.
By October 2000, 20th Century Fox had hired Konner and Rosenthal to simplify the Apes script written by William Broyles Jr., who had quit in August. Konner and Rosenthal were rewriting the script even as sets were being constructed. The title of the production changed from The Visitor back to its original title, Planet of the Apes. Various alternative endings were considered before the filmmakers decided on the final one. One of the considered endings had Leo Davidson crash-landing at Yankee Stadium, witnessing apes playing baseball. Despite the nature of his departure, Broyles "had a lot of respect with the work they did. And I think that given what I'd done and given what Tim wanted, they navigated the right course."
