Ben Wheatley has long been the British filmmaking equivalent of Evel Knievel, releasing wild experiments in genre that, while not always sticking the landing, remain impressive for their sheer audacity. Bulk continues that trend, a super-low-budget tribute to existentially loaded sci-fi (particularly Jean-Luc Godard’s Alphaville) that revels in a homemade charm and game performances from Sam Riley, Alexandra Maria Lara and Noah Taylor (who each play multiple characters with the simple joy of actors raiding their dressing-up box to put on a show). 

Where Wheatley’s past low-cost projects have been impressive for their resourcefulness (A Field In England, in particular, feels luxurious despite its meagre budget and tight shooting schedule), the practical effects here radiate the energy of a small boy moving his toys around a play pit, while sets are as basic as a well-crafted (and beautifully lit) student film.

In its finest moments, Bulk captures the magic of talented people having a great time together and welcoming audiences along for the ride. Almost inevitably, tolerance levels will vary for Wheatley’s deliberate indulgences, and a few too many meta-jokes about the nonsensical structure and messy plotting grate more than they entertain. But as a palate-cleanser after the mega-budget folly of Meg 2: The Trench, this is a deeply personal, enjoyably impish and somewhat mad work.
