Protagonist is a 2007 American documentary film about the parallels between human life and Euripidean dramatic structure. The film was written and directed by Jessica Yu.
It featured extensive interviews with terrorist Hans-Joachim Klein, ex-gay Christian evangelist Mark Pierpont, bank-robber Joe Loya, and martial-arts enthusiast Mark Salzman (the director's husband). Interspersed with the interviews are scenes from ancient Greek drama performed by puppets and narrated by Marina Sirtis and Chris Diamantopoulos.
