"Merlin" is back on Syfy tonight (Jan. 6th) with a whole new season. Fans were shocked to see Uther's (Anthony Head) death in the trailer, along with a much darker tone. Zap2it got to chat with stars Colin Morgan who plays Merlin and Katie McGrath who plays his archenemy Morgana about what's coming up for fans of the show.

Morgan said, "The 4th season definitely ups the game a lot, even in terms of how it looks ... it gets a little bit darker each year. This is the darkest it's become." The show has had dark episodes before, but they've always been balanced out with silly ones to break the tension....
