A documentary film festival with live music, screenings, poetry readings and performances will focus on theories, investigations and questions on the September 11th, 2001 attacks.

The festival is scheduled to begin at 4 p.m. Sunday, June 12th, at the Church in Ocean Park, 235 Hill St., Santa Monica. A $20 donation is requested at the door.

The festival is organized by “911truthla,” a group that doubts government accounts of the September 11th attacks.

Among the festival presentations will be Loose Change, directed by Dylan Avery, and a revised documentary Painful Deceptions, by researcher Eric Hufschmidt, which seeks to provide “scientific analysis” of the collapse of the World Trade Center buildings.

The comedy group “Billionaires for Bush,” which satirizes rich Republicans, will perform at the event. Musical guests include Tim Biancalana, who will perform his John Lennon tribute.

Reservations, (310) 470-4557.
