The stars Merlin have been talking to BBC Breakfast as the show continues its fifth series.

It follows the adventures of the young wizard as he helps King Arthur and the knights of the round table govern Camelot.

The actors Colin Morgan (Merlin) and Alexander Vlahos (Mordred) explained how the tales are popular because they have been given a modern twist.

Merlin is on BBC1 at 8.20pm on Saturday.
