In conjunction with Kudrow's production company Is or Isn't Entertainment and the U.K.'s Wall to Wall productions, the new show is an adaptation of the hit, award-winning British television documentary series of the same name. NBC said "Who Do You Think You Are?" is intended to "lead celebrities on a journey of self-discovery as they unearth their family trees that reveal surprising, inspiring and even tragic stories that often are linked to crucial events in American history."
