Another year, another outrageous oversight from the documentary branch of the Academy. Today AMPAS announced the 15 films that will contend for next year’s five Best Documentary Feature slots, and although there are several worthy films included (Waiting for “Superman”, Inside Job, Exit Through the Gift Shop, and The Tillman Story among them), missing from the list was the acclaimed exposé Joan Rivers: A Piece of Work, one of the sweetest and most fascinating films, unscripted or otherwise, of the year. Also MIA: The Facebook-fueled Catfish, the transgender family tale Prodigal Sons, and the political eye-opener 8: The Mormon Proposition. Given its strong reviews, I was surprised Lucy Walker’s Countdown to Zero wasn’t included, though her Sundance prize-winner, Waste Land, did make the cut. (For the record, an Academy spokeswoman tells me that the Joaquin Phoenix doc I’m Still Here was not submitted for consideration in this category.)
