My Three Sons

At Fred MacMurray's insistence, all episodes were filmed out of sequence during the show's entire run using a technique now known as the MacMurray method. MacMurray would do all of his scenes in 65 nonconsecutive days. The cast regulars got haircuts once a week in order to maintain continuity. Guest stars would have to return months later to complete an episode. All kitchen scenes would be done together, then all scenes in the upstairs hallway would be filmed together, etc. This fact was well concealed until Dawn Lyn joined the cast as Dodie. Her upper front teeth grew in irregularly during the entire 1969-70 season, from being barely visible in scenes with MacMurray to being plainly visible in scenes without him. William Frawley never felt comfortable with this method of filming, having grown accustomed to filming "I Love Lucy" in sequence during its entire run.

Frequent Continuity Errors. Due to the 'out of sequence' way they were making the show, there's sometimes evidence that scenes in any episode were filmed months apart and edited together, looking like it's set in a very short time.
