I can't help comparing this to how early Doctor Who was shot back in the '60s. They recorded on videotape with fairly crude editing technology, so they basically had to do it like a live play, even cutting from one scene to the next in real time (with scripts structured to allow the actors time to move to a new set or change wardrobe while different actors were on camera). For some technical or budgetary reason, they were only allowed a maximum of three recording breaks per half-hour episode, so when a line or action was flubbed, they usually just had to keep going, unless it was drastic enough to require a retake. So they'd have to do about 24-25 minutes of acting in no more than four distinct sessions, for an average of at least six minutes per "take." I imagine they often recorded more than ten minutes straight through without a break.
Of course, they had several days of rehearsal during the week before they actually got around to shooting the episode, so they had plenty of time to memorize things. They actually recorded one episode per week, and when the cliffhanger from the end of one episode was recapped at the start of the next, they actually had to repeat the performance, whereas in later years they'd just replay the footage.
