He made one key early decision that has guided his approach to the show: no supernatural elements.....
“It wasn’t that I don’t like magic — I do,” Sorkin said. “Nor were there commercial reasons — no producer wants to put on a marquee, ‘Now With No Magic!’ It was because I feel that this story, in particular, had a chance of landing more powerfully, more emotionally, if people felt real. If a problem can be solved by waving a magic wand, it doesn’t feel like much of a problem.”
“When I first started writing it, I thought, there’s an easy way to solve this: Don’t sing the songs,” Sorkin said.
But Sher asked Sorkin to reconsider, given fan fondness for the score. “There’s a reason we see ‘Camelot’,” Sorkin acknowledged, “and the reason isn’t me.”
So he came up with an alternative solution: humor. The songs are back, preceded by dialogue in which Guenevere preemptively defuses their sting with Sorkin-esque wit."
