Well, there is one secret i can divulge about Barry Lyndon.It is a great secret. It is THE secret. In the film there is one beautiful view. It is at a spot dear to my heart. Where a friend flew boldly, majestically, with the wings of a giant bird, over the countryside below, and almost came to grief. But she was undaunted, for great was her courage.. and great was her reward. Once she was English, after that she was English no more. And that sir is the truth. There, behind the view in the film, lies a little road (barely a track) over the wild mountain behind where magic happens! It is not like other roads. No sir, it is not. I found out later- after my first unexpected taste of the magic- Joseph of Armithea is supposed to have turned back there. Oh yes, the Da Vinci Code barely scratched the surface. The truth is stranger, deeper than fiction. Merlin was also in those parts. And perhaps he still is. Turner the painter strode there in his youth, before he realised the sun is god. Little did he know, that track was the making of him. In the sky you will see the Red Kite. And along that track, there's an old priory, then a wide green beautiful valley with fine horses, then just past where the magic ends there are thousands of trout swimming together. A great secret indeed. And now, though many miles away, over the sea, i'm fearful for divulging; i fear the wrath. But beside me i have the little doll. And my heart is pure. And those with pure hearts need not fear the ways of the righteous. But those whose hearts are greedy shall never know the secret. Pain and sorrow will be their destiny, until such time when...

Deep deep is the magic that guards the secret, and it shall be safe from the wicked. Forever.

A Touch of Zen (King Hu) may fit this thread. A certain mysticism perched between Crouching Tiger + Jodorowsky's Holy Mountain. 

Oh, and the picaresque, Bunuelesque, Quixotesque, ghostly, gothic, slightly erotic Polish labyrinthine-Borgesian shaggy dog, Chinese box (Diderot-esque?) period adventure set in Spain with a Belgian protagonist; The Saragossa Manuscript.

or another from Poland, Mother Joan of the Angels, about some naughty nuns in need of exorcism. 

Central/Eastern Europe seems to be the place for the weird + surreal.
