Since the 1980s, Tom Fontana has been changing television. The medical drama St. Elsewhere, one of the first ensemble series, demystified the concept that doctors are infallible. Oz, with its gritty depiction of prison life and its flawed characters, was HBO’s first original series. Borgia and Copper, Fontana’s current shows, represent new models of international co-production. In this video interview, Fontana talks about his experiences with working on Oz and Borgia. He also discusses the benefits and challenges of working with international partners.
