Mister Wonderland recounts the remarkable story of Sylvester Z. Poli, a humble artisan who emigrated from Italy to America at the end of the 19th century — only to become the greatest theater impresario of his time. The film chronicles his journey from rural Tuscany to the bright lights of the Roaring Twenties, revealing how a migrant’s ingenuity shaped the movie-going experience as we know it. Crossing continents and generations, Mister Wonderland sets out to find what remains today of Sylvester’s theaters and the communities they used to serve.
