If you missed local writer Nick Flynn’s appearance in Boston last week, you have another shot to ask him questions about his memoir. Flynn, whose book is now a movie called “Being Flynn,’’ will appear at a Ploughshares event at Emerson College on April 4. . . . Local director Arthur Luhn, who made the movie “Conned,’’ is shooting a film around Massachusetts this summer called “The House Across the Street.’’ It will star Jessica Sonneborn and J osh Hammond, who was in “Jeepers Creepers II.’’
