Alan Ball’s button-pushing “Nothing is Private” has been retitled “Towelhead” and will show under that title at next month’s (!) Sundance Film Festival. The film world premiered as “Nothing” at the Toronto Film Festival, where commentators as diverse as Roger Friedman and Stu Van Airsdale were frothing about its depiction of a 13-year-old Arab-American girl who is sexually abused by an Army reservist played by Aaron Eckhardt. I’m told Warner Independent will distribute the flick, which I admired, under the title of the original book it’s based on. Meanwhile, The Motion Picture Group has announced that Deborah Kampmeir has completed a new edit of this year’s Sundance cause celebre, which is still called “Hounddog” (aka “The Dakota Fanning Rape Movie”) “and is ready to screen it for distributors with the intention of completing a sale.” So far, no takers we know of.
