Evilspeak is a 1981 American horror film directed by Eric Weston and co-written by Weston and Joseph Garofalo.

Upon finding a book of black mass that belonged to the evil medieval Father Esteban, he taps through a computer to conjure Satan and summons spells and demons to get revenge upon his harassers.
