Night Train to Venice
While it features such high-grade actors as Hugh Grant and Malcolm McDowell, it is a veritable mess. The plot is nonlinear to say the least, jumping all over and on top of its own story. The style is Gothic and it seems to be hinting at the commedia dell'arte, but it has no coherent logic to it.
It is a collection of obscure icons, senseless scenes, Venetian masks, neo-Nazis, vampires (I think) and bloodthirsty Rottweilers. I have still no idea what the story was about, and even the Wikipedia page has difficulties describing the plot.
Such as it is.
The only positive thing I remember about it is scenes where the camera follows and flies along a flock of doves in Venice, shot in a pre-drone time.
Beyond that I have the feeling someone dropped the original script, mixed up the pages and then they shot it in a backwards order and called it an 'art film' which is a normal title for films that make no sense.
Grant himself has proclaimed it the 'worst' he's ever done.
