Merlin has become a flagship programme for the BBC in recent years and season 4 can currently be seen on a Saturday night.
And this series sees the return of Rupert Young as Sir Leon and Tom Hopper as Sir Percival - loyal knights of Camelot.
Season 4 sees huge changes come to Camelot while the Knights are once again called to do battle to protect the land and the crown.
We caught up with Rupert and Tom to talk about what lies ahead for the knights, how relationships change and the fun that they have on set.
