There is no excuse for such an unbelievably bad and cheesy film when it stars no less than the likes of Malcolm McDowell, Rupert Everett, Edward Woodward, Dyan Cannon and even, of all people, Liam Neeson!
And yet bad it is! The dialogue is appalling. The plot ambles along non-sensically until the producers in desperation obviously cried 'For God's sake rap this mess up - I don't care how you do it - just make it stop!'
And as for the acting - if bad actors chew the furniture - these Hollywood heavyweights devour 'ye olde' oak scenery in a ravenous frenzy!
Add to that the kind of special effects that Ed Wood would have been ashamed of and you have an abysmal movie.
And yet for all that it is precisely so bad it's good!
You'll laugh at the normally suave Rupert Everett in his lobotomy hiding, Mickey Mouse club reject helmet!
You'll chuckle as Malcolm McDowell fights the undead knight who looks like a doctor's waiting room prop from a Les Dawson sketch - especially when he disappears in a puff of smoke and the camera visibly shifts position from one shot to the next.
You'll cheer at Edward Woodwardwardwood's excellently OTT 'I graduated from the school of shouting' Wicker Man acting.
You'll retch as Gawain gives the most stomach-churningly, sickening lovey-dovey dialogue as he marries the once cursed Lady Ragnall.
You'll giggle as Rupert Everett's Lancelot fights what is patently a man in a latex dragon suit.
But above all the star of the show must be Liam Neeson's unspeakably bad barbarian. Who would have guessed this actor would have gone on to move millions as Oscar Schindler. The crowning moment has to be when he (as bear skin-clad barbarian, Grak) says to Guinevere "Mmmm, you woman of spirit! Me like that!"
