‘Mad Hot Ballroom’ 10th Anniversary Celebration

The Washington Heights neighborhood is probably better known for salsa than for the foxtrot, but that didn’t prevent the fourth and fifth graders at Public School 115 from mastering that dance in the 2005 documentary “Mad Hot Ballroom.” The film, by Marilyn Agrelo, chronicled the students’ preparations for a citywide dance contest, and a number of them will attend this free anniversary celebration, along with their instructors, the filmmakers and children currently enrolled in Dancing Classrooms, the program that taught ballroom techniques to the movie’s subjects. The event will include preshow dance lessons and demonstrations and a question-and-answer period afterward.
