The BBC have gone and made our morning, by releasing the first trailer for series 5 of hit drama Merlin.

BRADLEY JAMES LOOKS WELL BUFF.

The slow-mo bit where he walks in wearing full armour as a Muse track plays in the background made us go a bit weak at the knees.

Colin Morgan is also back in action as Merlin, and it seems things are getting all kinds of tense and dramatic over in Camelot these days.

Katie McGrath who plays Morgana, revealed in a recent interview that the new series will have a much more adult feel too, which suggests shiz is gonna get DARK.

"It's a three-year time-jump, so... we're all older," she said. "We were playing... very early 20s at the start, now I feel like we've all started to play adults, which for us is a great change."

Watch the trailer below, and then answer our VERY IMPORTANT QUESTION - who is hotter, Bradley James or Colin Morgan?

Series Five of Merlin is expected to hit telly screens in late 2012.
