What, you thought Hungary would be the only European country that doesn't have its own King Arthur adaptation?
Sárkány és papucs (Dragon and slipper, 1989) is a feature length animated movie set in King Arthur's court. It is introduced and narrated by the court jester, who tells us all up front that he is the sanest person in Camelot.
He is not wrong.
King Arthur's days are taken up by his boys' club - he spends all his time in their company, watching jousting matches and regaling the knights with his abysmal storytelling skills. Queen Ginevra, in the meantime, feels completely neglected (she doesn't even remember when she was last kissed) and shares her distress with Peggy, the clever handmaiden. The two women order a love potion from Merlin to rekindle Arthur's love for his wife - however, the pudding the potion is baked into accidentally ends up on Sir Lancelot's plate.
(Or, rather, King Arthur pawns it off to his friend, saying Ginevra is a horrible cook, and plums are bad for the digestion anyway)
The (overdosed) love potion turns Lancelot into a raving madman - there is a 3 minute long scene of him just screaming GINEVRAAAA all over Camelot at night (which is mostly what the movie is known for among distressed parents with small children). Peggy cries her eyes out (she is in love with Lancelot) and the Queen is worn down by the knight's advances - she loses sleep, then her hair, then her teeth, until finally her entire tower is set on fire by Lancelot's burning love message. The Queen complains to Arthur (who is the only person completely oblivious of what's going on), and gives him an ultimatum: Either her, or Lancelot.
The most quotable moment comes from the dragon's landlady, Matildka, an old hag who refuses to let Sir Lancelot inside in the absence of the dragon. Lancelot calls Goliat "Doctor" since the sign outside his lair reads "DR. GOLIAT." The hag corrects him:
"Not doctor. Draco! Draco, draconis, masculine. Don't you speak Latin?! Go to hell, then."
It was a very applicable quote all through my college Latin studies. Incidentally, it is also applicable to professors in certain contexts.
Similarly quotable is Lancelot's resigned steed Oliver, who does not want to do any of the questing business (and simply calls his owner "the idiot"). His go-to response to everything is "Well, this is stupid... but what can a horse do about it?..."
