The stars of Fringe are Anna Torv, John Noble and Joshua Jackson. The show is really an update of Fox's The X-Files with a more complicated "mythology" back story and even wilder, more unbelievable phenomenon. It varies between frankly ridiculous plots but it's the acting and the relationships between the characters which has me hooked. It airs Friday nights at 9pm.
Now, happily, the news has been announced that Fringe has been renewed for a fifth and final season (of 13 episodes).
