The City Paper has a Pavlovian response to the month of April and the start of spring. As soon as that warm weather hits, we get a hankering for hanging a projection screen in Marion Square and offering free film screenings to anyone in Charleston with a picnic blanket or folding chair or butt to sit on. We’ll open our month-long program with the Oscar-winning Martin Scorcese film Hugo. Set in 1920s Paris, the film is an ode to the beginnings of the film industry. Unfortunately, we can’t show the movie in all of its 3-D glory as intended, but it’ll still make for a fun night. Each week, you can also try food from Roti Rolls, D’Allesandro’s, Hello My Name is BBQ, the Taco Spot, O-Ku, and King of Pops, plus beer from New Belgium. Trek is sponsoring a bike valet, so ride over on two wheels, not four. The night is sponsored by the Charleston Trident Association of Realtors, who will be accepting donations for the nonprofit REALTORS Housing Opportunities Fund as well as for a school supply drive for James Simons Elementary.
