Hollywood accounting is bizarre and obscure at the best of times, but this is an extreme example. CBS has pre-sold the show to Space in Canada and to Netflix in pretty much the rest of the world. Combined with a recent bump in subscribers to CBS All Access (where the show will debut), taking it over two million subscribers, this has made the show profitable. It is currently in pre-production in Toronto with filming next expected to start until September.
As part the announcement, CBS also confirmed that Season 1 of the show will consist of thirteen episodes.
