Harpur Cinema’s “Forces of Nature” series features “A Different Path” (Monteith McCollum, USA, 2010), a film by a member of the Binghamton University Cinema Department, at 7:30 p.m. Friday, March 15, and Sunday, March 17, in LH-6. In “A Different Path,” sidewalk activist senior, a critical mass trumpeter, city kayaker and others, use ingenuity and humor to solve their modern mobility dilemmas in an automobile-centric environment. Combining animation, cinematography and original music composed by McCollum, adjunct lecturer of cinema, and performed by Michael Louis Johnson, this film is an artistic and poetic treatment of personal struggle and environmental concern over livable cities. Special note: McCollum will introduce the film on Friday, March 15, and will answer questions after the screening. Premiered at South by Southwest in 2010 and was nominated for the Pare Lorentz Award of the International Documentary Association. Admission is $4.
