Massacre at Central High (released as Blackboard Massacre in the UK) is a 1976 American horror thriller film directed by Rene Daalder and starring Derrel Maury, Kimberly Beck, Robert Carradine, and Andrew Stevens. The plot follows a series of revenge killings at a fictional American high school, after which the oppressed students take on the role of their bully oppressors. Despite its title, it is not a slasher film but an unusual blend of political allegory, social commentary, and low-budget exploitation; with the exception of the final sequence, no "adult" characters (such as teachers and parents) are seen.
