Tideland is a 2005 fantasy film co-written and directed by Terry Gilliam, following the story of Jeliza-Rose, a young child who struggles to make sense of life in isolation as she lives with an eccentric adult brother and sister in rural Texas after the death of her drug-addicted, abusive parents. It is an adaptation of Mitch Cullin's novel of the same name. The film was shot in Regina, Saskatchewan, Canada, and the surrounding area in late 2004. The world premiere was at the 2005 Toronto International Film Festival where the film received a mixed response from both viewers and critics. After little interest from U.S. distributors, THINKFilm picked the film up for a U.S. release date in October 2006. Despite the film's eclectic and unconventional themes, which included child abuse, decomposition, incest, flatulence, mental illnesses and heroin usage, Tideland featured a number of notable actors, including Jennifer Tilly, Jeff Bridges, and Janet McTeer.
