Improvised Downton Abbey: Enter the world of a privileged but troubled English estate set in the early 20th century. It's a world inspired by the hit PBS show Downton Abbey, but you won't see Sybil, Matthew, or Violet. Instead, you'll be surprised by new and completely improvised characters and stories, all created on the spot and inspired by audience suggestions.
Founded in 1986, BATS has become the premier improvisational performing company and improv training school in the Bay Area, attracting more than 12,000 audience members and 1,300 workshop enrollments every year.
