Searching for The Wrong-Eyed Jesus (2005)
Directed by Andrew Douglas
Searching for The Wrong-Eyed Jesus is a captivating and compelling road trip through the creative spirit of the the South of the USA. Director Andrew Douglas's film follows "Alt" Country singer through a gritty terrain of churches, prisons, truckstops, biker bars and coalmines. This journey takes you through a very real contemporary Southern America, a world of marginalised white people and their unique and homemade culture. Along the way are roadside encounters with present-day musical mavericks including The Handsome Family, Johnny Dowd, 16 Horsepower and David Johansen; oldtime banjo player Lee sexton; ockabilly and mountain Gospel churches - and novelist Harry Crews telling grisly stories down a dirt track.
