Amy Sherman Palladino and her husband, Dan Palladino, are deep in production for season three of their hit show on Amazon, “The Marvelous Mrs. Maisel.” It’s the story of Midge Maisel as she pursues a career in stand-up comedy in 1960s New York. The pair have already won a ton of awards for the show, including Emmys and a Peabody. They talk to us about the joys of producing a show for a streaming company, why no detail is too small to notice and how Midge’s story will end.
