Worldbuilding Inside a Snow Globe

Tom Fontana is a TV writer and producer who worked on St. Elsewhere in the 1980s. The show was a pretty straightforward hospital drama, but Fontana had a mischievous streak -- and a soft spot for crossovers. So when he came up with a trick ending to the show, revealing the entire series had been the fantasy of an autistic boy named Tommy Westphall peering into his snow globe, Fontana had no idea that episode would lead to a unified theory of television. With Keith Gow, Tom Fontana, Bill Lobley and Robb Pruitt. A version of this piece first aired on PRIs Studio 360.  Learn more about your ad choices.
