HBO Documentary Films acquired domestic TV rights to My Trip to Al Qaeda, the Alex Gibney-directed docu that is based on the one-man play by journalist Lawrence Wright and his effort to remain objective covering the rise of fundamentalist Islam after 9/11. The documentary is one of three Gibney films premiering at Tribeca. Gibney’s also showing a work print of his documentary about the scandalous rise and fall of New York State Governor Eliot Spitzer, a film that is being shopped by John Sloss, whose Cinetic made the HBO deal. Gibney also directed a segment of Freakonomics, also on the Tribeca sked.
