I read on indieWIRE yesterday that the Academy of Motion Picture Arts and Sciences (aka The Oscars) narrowed their list of top documentaries down to 15.  Of that 15, six were here at Sundance last year.  Of that six, FIVE appeared on Park City Television shows.

Just goes to show that we know what we're doing (or at least Sundance producer/booker/host Ori Hoffer does).
The 15 films on the "short list" are (Sundance films in red):
"At the Death House Door, directed by Peter Gilbert and Steve James
"The Betrayal" (Nerakhoon), directed by Ellen Kuras
"Blessed Is the Match: The Life and Death of Hannah Senesh", directed by Roberta Grossman
"Encounters at the End of the World", directed by Werner Herzog
"Fuel", directed by Josh Tickell (watch interview)
"The Garden", directed by Scott Hamilton Kennedy
"Glass: A Portrait of Philip in Twelve Parts", directed by Scott Hicks
"I.O.U.S.A.", directed by Patrick Creadon
"In a Dream", directed by Jeremiah Zagar
"Made in America", directed by Stacy Peralta
Man on Wire", directed by James Marsh
"Pray the Devil Back to Hell", directed by Gini Reticker
"Standard Operating Procedure", directed by Errol Morris
"They Killed Sister Dorothy", directed by Daniel Junge
"Trouble the Water", directed by Carl Deal and Tia Lessin
