The BBC has released a lot of new information concerning the upcoming fourth series of Torchwood, which has been renamed from Torchwood: The New World to the new title of Torchwood: Miracle Day. Some of the information included could be seen as spoilers, so bear this in mind if you’re trying to remain spoiler-free for the new season!

Along with new cast member Mekhi Phifer who will be acting as CIA operative Rex Matheson, John Barrowman (Captain Jack Harkness) and Eve Myles (Gwen Cooper) have been joined by Bill Pullman (Independence Day) portraying protagonist Oswald Danes, Arlene Tur (Crash) portraying Dr. Vera Juarez, and Alexa Havins portraying Agent Esther Drummond.

As indicated by the character descriptions released by the BBC, the events that bring Captain Jack back to Earth and draw Gwen Cooper back into the world of Torchwood surround a mysterious event that would become known as Miracle Day — forcing the heroes, notably Gwen, to make some very challenging and “terrible decisions” for humankind. Essentially, Miracle Day ties into a global conspiracy being scrutinized by Rex Matheson and Esther Drummond.
