The Secret Cinema creators will host three major events at the festival, including the grand finale of its Bugsy Malone show, The Other Cinema's presentation of La Haine with a live score from Asian Dub Foundation and a surprise guest at the woodland glades.
Future Cinema founder Fabien Riggall said: "We are really excited to come to Wilderness Festival, which we see as one of the most exciting new arts festivals around.
"We are looking to transform the entire site into Bugsy Malone for the opening night with the biggest splurge fight ever staged, then creating a secret event in the woods on the Saturday night and closing with the incredible Asian Dub Foundation playing live to La Haine on Sunday."
Wilderness organiser Tim Harvey added: "Wilderness has always sought to break the normal conventions of mainstream festivals and this exclusive festival film partnership does exactly that.
"For us, it's about delivering cultural experiences that are individually tailored to the majestic landscape of Cornbury Park and we're delighted to have the Future Cinema team create a series of truly ambitious cinematic happenings over each of the three days this August.
"The Bugsy takeover on Friday night will be an astonishing spectacle and one that adds yet another really unique dimension to the show and we look forward to welcoming both Future Cinema and Secret Cinema's audience to Wilderness this August."
Wilderness takes place at Cornbury Park in Oxfordshire from August 10 to 12.
As previously announced, it is headlined in 2012 by Spiritualized, Wilco and Rodrigo Y Gabriela featuring C.U.B.A.
