Could it be something Slipknot?

I saw it on UK TV, but I was already an adult at the time.

The Seventeenth Lord of Merician, Simonius Ravenbeard, brought his fist down on the arm of his throne. "ENOW!" he bellowed. "I WILL NOT SEND MY SON TO HIS POTENTIAL DOOM ON THE WORD OF SOME SMOKE-ADDLED CHRONOMANCER, AND THAT IS AN END TO IT!"

Chronicler Nai-Ralev drew a sharp breath. "I seem to remember, My Lord, that you were a lot more receptive to-"

"DO NOT consider Finishing that sentence," Ravenbeard sternly said, "unless you intend to become acquainted with Stable duty, OR you are recommending something from the kitchens to soothe my temper."

"Perhaps then," the Chronicler smiled a conniving smile, "You, my Lord, would accept this challenge in his stead?"

"Well if that's the case," Ravenbeard's mood brightening, "why didn't you say so in the first place?"

"My Love", interrupted the Queen, "Have you no Faith in our son?"

"I have every faith in our Son," Ravenbeard said, Diplomatically, "to handle anything from enemy soldiers to Armoured Ogres, but the Dark Lord himself is no job for a veritable Neophyte, even one of my own Considerably, er, "enhanced", Bloodline. And would I not have Merician's Premier elven Mage at my side?"

Usha Raven blushed slightly.

"Then it is Decided!" Said the king, picking up his sword.

After all, the prophecy said that a union of Swarthenboch and Elf would be the combination needed to end the reign of darkness at the edge of Merician. Still, Breneric, their son, would not be denied.

But the great legend that is the defeat of the Dark Lord, is an epic in and of itself...
