text: Filming locations The pilot season was shot entirely on location in Dallas, Texas, and at the Cloyce Box Ranch in Frisco, Texas. Later, most interiors for the show were shot at the MGM Studios in Culver City, California (which was purchased outright by Lorimar in 1986), with some exteriors being shot at the Southfork Ranch in Parker, Texas, and other sections of Dallas. For season 13, rising production costs led to all filming being relocated to California. Typically the cast and crew would spend six to eight weeks filming on-location sequences in the Dallas area during the summer prior to the season, then film the remainder of the season in the Los Angeles area; fewer than half of the episodes in a given season had on-location sequences filmed in Dallas. MGM built a full-size replica of the Southfork Ranch backyard and pool on one of its soundstages, allowing for filming of "location" shots during the latter part of the season.
  Directors
  Leonard Katzman is the most prominent director on the show, having directed episodes of every season except seasons 1, 9 and 12. Next to Katzman, Michael Preece, is responsible for having directed the most Dallas episodes, having joined the show during season 4 and remaining until the end. Of the two directors attached to the original miniseries, Robert Day did not return for subsequent seasons, while Irving J. Moore remained on the show until season 5, and then returned for the final three.
  Five of the series' stars also directed episodes: Larry Hagman (seasons 3-14), Patrick Duffy (seasons 4-8 and 10-14), Linda Gray (seasons 9-12), Steve Kanaly (seasons 10-12) and Ken Kercheval (seasons 13-14).

  Dallas originally aired on Saturday nights when it debuted as a regular series. Within a month, the show was moved to Sunday nights, where it stayed until halfway through the season, when it took a Friday-night slot. Dallas remained on Fridays until the show ended in 1991, alternating between 9p.m. and 10p.m. airings.
