Disputes broke out during the filming. Cinematographer Russell Metty, a veteran with experience working in big pictures such as Orson Welles' "The Stranger" (1946) and "Touch of Evil" (1958) and Howard Hawks's "Bringing Up Baby" (1938), complained about Kubrick's unusually precise and detailed instructions for the film's camerawork and disagreed with Kubrick's use of light. On one occasion he threatened to quit to Ed Muhl, to which Kubrick told him: "You can do your job by sitting in your chair and shutting up. I'll be the director of photography." Metty later muted his criticisms after winning the Oscar for Best Cinematography. Kubrick wanted to shoot at a slow pace of two camera set-ups a day, but the studio insisted that he do 32; a compromise of eight had to be made. Kubrick and Trumbo fought constantly over the screenplay. Kubrick complained that the character of Spartacus had no faults or quirks.
