The Tripper Trailer (2007)
The film is a nostalgic homage to the exploitation films of Wes Craven and Tobe Hooper that follows a group of free-loving hippies who escape to a modern-day Woodstock for a weekend of debauchery, only to be stalked by a radical-minded psychopath with an eerie resemblance to Ronald Reagan, the 40th President of the United States.
