Bug is a play by American playwright Tracy Letts. Exploring themes of paranoia and conspiracy theories, the play tells the story of a woman who, as she spends time with a newly acquainted man in her motel room, starts sharing more and more of his paranoias. It premiered in London 1996, and was also performed around the United States between 2000 and 2004. The play was adapted into a film of the same name directed by William Friedkin in 2006, with Letts writing the screenplay and Michael Shannon, who had played the male lead role of Peter in the original London production and in some American versions, reprising his role.
