Guild strike, given Benchley was not unionized. Overall, he wrote three drafts before the script was turned over to other writers; delivering his final version to Spielberg, he declared, "I'm written out on this, and that's the best I can do." Benchley later described his contribution to the finished film as "the storyline and the ocean stuff—basically, the mechanics", given he "didn't know how to put the character texture into a screenplay." One of his changes was to remove the novel's adulterous affair between Ellen Brody and Matt Hooper, at the suggestion of Spielberg, who feared it would compromise the camaraderie between the men on the Orca. During the film's production, Benchley agreed to return and play a small onscreen role as a reporter. Spielberg, who felt that the characters in Benchley's script were still unlikable, invited the young screenwriter John Byrum to do a rewrite, but he declined the offer. Columbo creators William Link and Richard Levinson also declined Spielberg's invitation. Tony and Pulitzer Prize-winning playwright Howard Sackler was in Los Angeles when the filmmakers began looking for another writer and offered to do an uncredited rewrite; since the producers and Spielberg were unhappy with Benchley's drafts, they quickly agreed. At the suggestion of Spielberg, Brody's characterization made him afraid of water, "coming from an urban jungle to find something more terrifying off this placid island near Massachusetts." Spielberg wanted "some levity" in Jaws, humor that would avoid making it "a dark sea hunt", so he turned to his friend Carl Gottlieb, a comedy writer-actor then working on the sitcom The Odd Couple. Spielberg sent Gottlieb a script, asking what the writer would change and if there was a role he would be interested in performing. Gottlieb sent Spielberg three pages of notes, and picked the part of Meadows, the politically connected editor of the local paper. He passed the audition one week before Spielberg took him to meet the producers regarding a writing job. While the deal was initially for a "one-week dialogue polish", Gottlieb eventually became the primary screenwriter, rewriting the entire script during a nine-week period of principal photography. The script for each scene was typically finished the night before it was shot, after Gottlieb had dinner with Spielberg and members of the cast and crew to decide what would go into the film. Many pieces of dialogue originated from the actors' improvisations during these meals;
