My Three Sons - Production Schedule

Production Schedule

The series was initially filmed at Desilu Studios in Hollywood, but at the start of the 1967–68 season, the cast and crew up-anchored and began filming the series at the CBS Studio Center in Studio City, California. The reasons behind this move were because actress-comedienne Lucille Ball had sold her studios to the Gulf + Western conglomerate, who owned Paramount Pictures, so Don Fedderson Productions, who produced My Three Sons (along with Family Affair starring Brian Keith), had to quickly make other arrangements for filming. The move also necessitated moves in the show's storyline as well.

Fred MacMurray was the only actor to appear in every episode of the series. Reportedly, MacMurray's contract stipulated that he work only 65 days per year. His scenes for each season were produced in two blocks of filming. He would report to the Desilu-Gower lot in late May and work 35 days (five days per week, weekends off), then take off for 10 weeks. He would then return to complete his remaining 30 days of shooting and was finished altogether around Thanksgiving. MacMurray's ten-week hiatus in the middle of each season's production schedule freed up the actor to follow other pursuits, while the filming of scenes with the other cast members continued. In short, all episodes were filmed out of sequence. Evidence of this is very apparent in several episodes, where plotlines had MacMurray's character on a business trip (e.g. "Small Adventure") or spending much of his time at the office (e.g. "Soap Box Derby"). This allowed him to seemingly take part in the entire episode with limited or no interaction with the other regulars during filming. This sometimes produced noticeable continuity problems onscreen, especially as the boys grew and changed styles. William Frawley, for one, never felt comfortable with this filming method, having grown accustomed to filming I Love Lucy in sequence.
