La Dialectique Peut-Elle Casser Des Briques?, in English, "Can Dialectics Break Bricks?", is a 1973 Situationist film produced by the French director René Viénet which explores the development of class conflict through revolutionary agitation against a backdrop of graphic kung-fu fighting. The film uses 1972 martial arts film The Crush (唐手跆拳道) by Tu Guangqi for its visuals which has been dubbed over by the filmmakers in an attempt at detournement. The concept and motivation of this film was to adapt a "spectacular" film into a radical critique of cultural hegemony and thus into tools of subversive revolutionary ideals.
