To promote season 2 of Westworld, HBO recreated the fictional Wild West town from the TV show just outside Austin at the SXSW festival, and they hired actors to play androids who think they're living in the Old West -- just like the androids on the TV show. The SXSW Westworld Experience was advertised as "Live Without Limits." Unfortunately, some of the guests took that slogan to heart. Featuring actors Alan Nelson, Liz Waters and Courtney Rose Kline. Also professors Noson Yanofsky, James South and Kim Engels discuss why an ancient Greek philosophical debate ties back to Westworld, the New York Yankees and whether you chose to buy a Cinnamon Danish. Learn more about your ad choices.

Avengers: Infinity War brought together characters from across the Marvel universe, but many of them already shared a common bond -- their creator Jack Kirby. While Kirby is best known for his intense drawing style, he was also a great storyteller who worked with Stan Lee to redefine what a comic book character could be. But their relationship was fraught. I talk with comic book experts Charles Hatfield, Mark Evanier, Randolph Hoppe, and Arlen Schumer about where we can see Jack Kirby's influence on the Marvel Cinematic Universe. And I explore Kirby's childhood at the Tenement Museum on the Lower East Side of Manhattan. Learn more about your ad choices. Visit megaphone.fm/adchoices

People have fantasized for ages about what it would be like to live in space -- whether it's living on the moon or Mars or on a space station. And if Elon Musk or Jeff Bezos achieve their goals with Space X and Blue Origin, life in space might not be science fiction anymore. I look at two different dreams of living outside the Earth and how close they are to becoming reality, from the impossibly curved space habitats of Gerard K. O'Neill to a city on the moon that might split apart. Featuring Robert Smith of the Space Studies Institute, artist Don Davis, and performers Jose Gonzales and Camille Hartmetz at Emerge, an annual event from Arizona State University's Center for Science and the Imagination.Learn more about your ad choices.

Philip K. Dick is best known for his fiction that have been adapted to movies and TV shows like Blade Runner, Minority Report and Man in the High Castle. He wrote about multiple realities and fantastic worlds beyond the scope of our mundane everyday lives. But he also believed that he experienced one of those alternate realities in the winter of 1974. The problem is, he couldn't figure out which paranormal experience he had. Professor Richard Doyle, author Erik Davis and playwright Victoria Stewart discuss how one of the most influential science fiction authors of all time became a character in one of his own novels.Learn more about your ad choices.

The holy grail for many animators is to create digital humans that can pass for the real thing -- in other words to cross the "uncanny valley." The problem is that the closer they get to realism, the more those almost-real humans repulse us. Blame evolution for that. I talk with Hal Hickel from ILM who brought Peter Cushing to life on Rogue One, Marianne Hayden who worked on games like The Last of Us and Uncharted for Naughty Dog studios, Vladimir Mastilovic from 3Lateral studios who worked on Hellblade: Senua's Sacrifice, and SVA instructor Terrence Masson about what it takes to cross that valley.Learn more about your ad choices.

Ursula K. Le Guin was a master storyteller who was best known for her "thought experiments" -- like what if there were a planet in which the inhabitants had no fixed gender? Or what if a man's dreams could alter reality around him? She was also a fearless critic, and a trailblazer. But she wasn't all that comfortable being on camera. That was the first of many challenges facing filmmaker Arwen Curry, who was determined to make a documentary about the author. I talked with Arwen about her film, Worlds of Ursula K. Le Guin, and how her subject became a mentor and a friend. (Correction from Arwen Curry: Ursula Le Guin had 3 brothers not 4, and the film will likely be on TV next Spring rather than the Fall.)Learn more about your ad choices.

They may not look scary to you, but the monsters on Doctor Who have scared generations of children to the point where hiding "behind the sofa" has become a meme in the UK. When I first started watching the show, I was baffled by one particular villain -- The Daleks. I didn't understand why they were The Doctor's arch nemesis, or why they were such a cultural phenomenon. After I learned more about their backstory, I began to realize that Doctor Who wouldn't work without them. Featuring Robin Bunce, Frank Collins, Nick Randell, Alyssa Franke, and cognitive scientists Deirdre Kelly and Jim Davies -- who debate whether it's worse to face a Dalek invasion or an invasion by the other big bad in the Doctor Who universe, The Cybermen. (This is the last episode in a three-part miniseries on Doctor Who.)Learn more about your ad choices. Visit megaphone.fm/adchoices

If The Doctor offered you a spot traveling with him on his spaceship/time machine The TARDIS, would you go? Would you still go if you knew what happened to all his previous companions? For many Doctor Who fans the answer to both questions is unequivocally yes. Traveling in the TARDIS will blow open your knowledge of the universe -- but you'll change in ways you can't begin to predict. In the second of my three-part series on Doctor Who, I look at whether The Doctor's companions are better off in the end, and why. Featuring Sarita Robinson, Emily Asher-Perrin, Alyssa Franke, Frank Collins, Nick Randell and Mac Rogers. Warning: spoilers ahead!Learn more about your ad choices. Visit megaphone.fm/adchoices

We don't know his real name. We don't know who he was before he stole the TARDIS -- a spaceship/time machine that looks like a police box on the outside, but is really a cavernous ship on the inside. He's thousands of years old, but wears a different face every few years. He calls himself The Doctor, but Doctor who? In the first of my three-part series, I look at how a restless intergalactic time traveller became a global pop culture icon, and why The Doctor's knack for physical regeneration resonates with fans on a more personal level. Featuring Andy Heidel, Nick Randell, Robin Bunce, Mac Rogers, Emily Asher-Perrin, Riley Silverman and Kelsey Jefferson Barrett. Learn more about your ad choices. Visit megaphone.fm/adchoices
