I caught Sword of the Valient on tv yesterday and ended up watching the whole thing as I couldn't believe how bad it was

From the tinny, slightly wonky tape of score to the tinny sound, bad acting and bad wigs it was hilarious. Unbelievably, Sean Connery was in it

The only stereotype missing was the dragon quest. In fact, I truley suspect this was where the Monty Python team got their screenplay for the Holy Grail
It got me wondering....was this the worst fantasy film ever, or do you know better?
