For someone who is a bit behind on Guy Maddin (and yes, that "someone" is me), Rumours is probably a bad place to begin. It also makes sense, as this is a lot more accessible than his prior catalog of silent films (a phrase I am comfortable using without the addition of "tribute" or "pastiche", because they're just that faithful to how silent cinema used to look), so I'm definitely not alone in starting here -- though I may have lost some cinephile cred in admitting this.
Regardless of how well you know your Maddin, this is certainly a movie with a lot of personality. It's hard to compare to any other film released this or any other year -- although I'm tempted to name one particular sequence "a better adaptation of Color Out of Space than the actual Color Out of Space movie".
Every location contains strange colors and magical mists; the music choices are bizarre to the point of idiosyncratic brilliance; the characters -- from the inexplicably British US president (Charles Dance) to the Swedish Secretary General (Alicia Vikander) who knows the forest's secrets -- are delightfully odd, but sometimes irritatingly unintelligible. (Cate Blanchett's performance, which has been described as an impression of Sandra Hüller doing an impression of Princess Diana, is particularly bemusing.)
It is also a pretty funny movie. For a while, at least. It loses some of its steam and satirical edge in the second half, seemingly getting bored of itself. Regardless, I am eager to check out more of this man's catalog and deeply ashamed that I have not.
