Submissions for the Mississippi Minute Film Festival are due online Thursday, Sept. 15, 5 p.m. They will be juried by Oct. 10 and awards will be announced and films projected on Oct. 24, 6 p.m. In celebration of the National Park Service’s Centennial, the Minneapolis Riverfront Partnership is expanding the Mississippi Minute Film Festival to include the entire 72 miles of the riverfront park. They invite those submitting films “to create a vision that tugs at heartstrings or makes people laugh and that showcases this mighty river and the National Park that winds through the metro area. Most importantly, they want the film to inform, energize and inspire this citizenry to action. All in 60 seconds or less.” For more information about the festival or locations for filming, visit www.minneapolisriverfront.org/riverfront-initiatives/mississippi-minute-film-festival/.
