Bloodthirsty Butchers (1970)

Sweeney Todd, a barber, and Maggie Lovett, a baker, join forces to commit a series of brutal, gory murders in London with a little help from Tobias Ragg, an employee of Maggie' bakery who abducts a number of customers from the barber shop and kills them and helps the couple make "meat pies" out of the dead victims for sale.
