Matt Harlock's debut feature arrives with a premise that could easily collapse into knowing wink-wink satire — blocked literary darling, Faustian double, David Fincher template, the whole kit. That it doesn't collapse is partly structural nerve and partly casting. Danny Horn plays Will Mercer, the kind of novelist whose debut novel earns breathless pull quotes and whose follow-up earns only paralysis. Joe Sims plays Mikey, the bullet-headed builder who materialises like a very handsome id in overalls. These two are doing different things in the same film, and that productive friction is where Blockhead lives. Harlock's central joke — that literary "danger" is a marketing category, not a lived condition — lands because the film commits to it architecturally, not just as a gag. Will types to a soundtrack of his own best reviews. His rants to creative-writing students attract a rapt protege. Publishers push books with pull quotes like "confrontational" and "dangerous" in a world where the most confrontational thing a novelist can do is go outside. Harlock is asking, with genuine satirical bite, how much muscle you can actually wield while hunched over a laptop. The Fincher debt is real and acknowledged, not denied. Following is the more precise comparison Harlock himself invites — Christopher Nolan's microbudget breakthrough about a writer who follows strangers until following has consequences. Blockhead walks similar streets but adds wit and a more explicitly satirical agenda. The Jekyll-and-Hyde scaffolding is present throughout: masks, screens, the stark contrast between the blank-page sparseness of Will's lodgings and the nocturnal world he strays into. One fairylights-over-a-balcony gag is properly Hitchcockian — the kind of touch that signals a filmmaker who knows the tradition they're working in. The wobbles are real and worth naming. A mid-film drug trip lands only partly, saved partially by a Coleridge namedrop that is either a clever justification or a very literary excuse — Harlock probably knows which and isn't saying. The mise en abyme structure that ties everything together is genuinely elegant, but it requires the film to earn its symmetry, which it mostly does. Horn holds the tempestuous bravado-and-insecurity balance well; Sims gets the better lines and seems to know it. What Blockhead actually achieves is rarer than its logline suggests: a first feature with a coherent visual argument, not just a coherent script. The world of the film — its production design choices, its use of night against blankness, its masks-and-screens motif — is doing satirical work that the dialogue doesn't have to carry alone. That's the sign of someone who can direct, not just write. First-feature wobbles and all, this is worth the evening.
