A play by Charles Dickens. The Haunted Mansion ride at Disneyland. A hologram of a famous dead pop singer. They’re all connected by a simple magic trick called Pepper’s Ghost. What’s most remarkable about this illusion is that it hasn’t changed much in over 160 years. I talk with Jim Steinmeyer and Ben Schrader, both designers of theatrical special effects, about why a Victorian magic trick is more popular than ever at modern theme parks and other live entertainment venues.

When Jim Henson hired Bonnie Erickson to design Muppets in the early 1970s, Bonnie had no idea this experimental project they were working on – a prime time TV show with puppets – would evolve into the cultural phenomenon of The Muppet Show. I talked with Bonnie about how the crew tried several one-off specials where they figured out who the main characters would be, what they’d look like, and what they’d sound like. Bonnie explains how she came up with the designs for Miss Piggy, Statler and Waldorf, Zoot and others. And we talk about one of the biggest challenges in making The Muppets seem believable – where to place the pupils in their eyes. This episode is sponsored by ExpressVPN. Our ad partner is Multitude.

This summer, Hayao Miyazaki will be releasing his final animated film before retiring. Environmental stewardship has been a consistent theme throughout his work, from My Neighbor Totoro to Spirited Away to Princess Mononoke. But what exactly has he been saying all this time about our relationship to the natural world? I gather a panel of experts to discuss the worlds that Miyazaki creates, and how his stories tap into current debates around the climate crisis. Featuring Yuan Pan, lecturer on Environmental Management at the University of Reading, and environmental journalists and authors Isaac Yuen and Emma Marris.   This episode is sponsored by ExpressVPN and Factor.

Discworld might be the most popular fantasy series you’ve never heard of. The late Terry Pratchett wrote 41 novels in the Discworld universe. To honor the 75th anniversary of his birth, we look at what fueled his satire, how he put himself into his characters, and why so many Discworld fans find solace and inspiration in his worldview. I talk with Pratchett’s former assistant and biographer Rob Wilkins, dramatist Stephen Briggs who adapted many Discworld novels to the stage, cultural critic Emmet Asher-Perrin and Professor Jacob Held, author of Philosophy and Terry Pratchett. Also featuring readings by Pavel Douglas. This episode is sponsored by BetterHelp and ExpressVPN. Our ad partner is Multitude.

Margaret Cavendish was a pioneer of modern science fiction – except she didn’t intend to write science fiction. In the 17th century, Cavendish was a noblewoman who wanted to be taken seriously as a philosopher. In her poetry and her landmark work, The Blazing World, she imagined parallel universes, microscopic cities, human animal hybrids, zombie armies and flying vehicles. I talk with professors Emily Thomas (Durham University), Lisa Walters (University of Queensland), Lisa Sarasohn (Oregon State University), and Lara Dodds (Mississippi State University) about why Cavendish wrote for future generations that she hoped would understand and appreciate her ideas.
