When a documentary filmmaker’s subject turns out to be reluctant and elusive, he desperately turns to alternative (and ethically questionable) methods to continue his film. But when his subject accidentally becomes an overnight internet sensation it sends him, and the film itself, down a maddening spiral of loose ends, selfishness, confusion, cello music, and existential despair. Cinema, truth, and friendship are put on trial in this blurry mixture of fact and fiction: like DAVID HOLZMAN’S DIARY meets Nick Broomfield, Ross McElwee, and Mr. Show. A meditation on documentary, autobiography, and celebrity in the 21st century, THIS IS A PORTRAIT, certainly…but of what?
