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 Hollywood, with some exteriors being shot at the Southfork Ranch in Parker, Texas, and other sections of Dallas. For seasons 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; less 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 the first, ninth and twelfth. Next to Katzman, Michael Preece, is responsible for having directed the most Dallas episodes, having joined the show during season four 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 the fifth season, and then returned for the final three.
Five of the series stars did also direct 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)
