Anyone who saw The Wolfpack at Tribeca or in theaters earlier this year was completely blown away by Crystal Moselle’s documentary about a band of shut-in brothers whose parents had all but imprisoned them inside of a Lower East Side housing project. The movie, just out on DVD and also available for download, has since become a sensation, with the Angulo brothers becoming almost as huge as the Hollywood stars they impersonated in their homegrown movie recreations. Now they’re the subject of “The Wolfpack Show” at Jeffrey Deitch’s space in Soho, and anyone who’s looking for inspiration for a Halloween costume (or inspiration in general) needs to go see it.
