Allegedly the "true story" of Juana de Castilla, the eldest daughter of the Catholic Queen Isabella (yes, the same who funded Columbus's expedition), the film charts the progress and degeneration of her morbid obsession with her husband, the Archduke Philip of Austria, known as "The Handsome" (and played in a rather unispired manner by Italian hunk Daniele Liotti, at his most buttery and beefy here). This is a groan-inducingly familiar story of late 15th c., early 16th c. intrigue, betrayal and bodice-ripping. It drips destructive lust from start to finish. But while La Reine Margot succeeds in making cruel sensuality and ruthless, cut-throat intrigue entertaining to watch, Juana La Loca just doesn't pull off. It just ends up feeling like a big-budgeted soap opera, with below-average, lazy or over-keen acting. Liotti looks positively bored and Pilar López de Ayala in the title role  though to be fair she may mature into a proper talent  just seems to be trying too hard, switching back and fourth from two-dimensional horny-looking to spoilt teenage hysterics all the way through. Some of the supporting cast are OK, with the exception of Manuela Arcuri, another Italian pin-up, voluptuous and beautiful but really no "actress" to speak of. I couldn't in fact bring myself to feel any concern towards any character, nor for that matter did I feel strongly in a negative way against any of the supposed villains. What a waste of a substantial film budget! This one, sadly, is just so rhetorical and deja-vu, nodding to other films in the genre rather than to its source material - history - for inspiration. It seems to me that such a fascinating and complex historic era deserved a far superior film-maker to evoke it.
