Whether Edgar Wright truly envisioned a three-feature rejoinder to Kryzsztof Kieslowski’s “Three Colours” trilogy — only with each film keyed to a different flavor of the British ice cream cone brand Cornetto instead of the colors of the French flag — is a matter of conjecture. The point is, we have his “Cornetto Trilogy” now (aka the “Blood and Ice Cream” trilogy), and the cinema is better for it. Wright’s first two features, Shaun of the Dead and Hot Fuzz, announced a remarkable comic talent who mixes visual hyperbole, a nimble, staccato cutting style, and a delight in all things geek culture, be they comic books, videogames or Italian cop movies. Yet his movies are elevated above mere reference-spotting by their droll humanism, their surprising melancholy undertone, and a pronounced pang of loss. You can see all three movies together in one sitting, all starring Simon Pegg and Nick Frost, capped by the 10 p.m. premiere of his latest, The World’s End. And since four Wrights don’t make a wrong, his non-Cornetto feature Scott Pilgrim vs. the World, one of the biggest cult movies of recent years, screens midnight Friday and Saturday at The Belcourt — where Wright turned up unannounced one Thanksgiving several years ago to catch The Last Waltz for the first time.
