Free film screening

What was the Minnesota Experimental City (MXC)? A futuristic attempt to solve urban issues by creating a full-size city — from scratch — in Minnesota’s northern woods. It was the vision of urban planner, geophysicist, University of Minnesota dean and comic book author Athelstan Spilhaus, whose efforts are documented in a film, “The Experimental City,” by Chad Freidrichs. Using retro film clips and archival material, Freidrichs’ film takes viewers back to the 1960s, when Spilhaus’ predictions of home computers and remote banking seemed more fantasy than reality.

A free screening of the film will be offered by the Minnesota chapter of Docomomo, a nonprofit organization devoted to the documentation and conservation of the modern movement. A free reception with snacks and beverages begins at 6 p.m. April 16, with screening of the 90-minute film at 6:30. A Q&A with curators from the Northwest Architectural Archives will follow the film. RSVP requested at: experimental-city.eventbrite.com. The event will be held at the Holden Center, Dunwoody College, 818 Dunwoody Av., Mpls.
