Red Kingdom Rising, newly reviewed on my main site, is a hugely impressive, visually poetic, British fantasy/horror feature from writer/director Navin Dev, whose previous shorts were Red Hood and Tree Man.
Inspired by the works of Lewis Carroll, Red Kingdom Rising tells of a young woman's return to her family home after her father's death and the secrets she discovers within herself. For much of the film there's an ambiguity - for both audience and protagonist - about what is or isn't a dream. Among the sequences that certainly are dreams are several quite gory nightmares with effects by Zombie Diaries' Mike Peel.
RKR had a preview last November, following which Navin was kind enough to send me a screener.
