Also in 1972, a four part animated television series was produced in Sweden, again based on the book "Agaton Sax and the Max Brothers". Adapted by Peggy Miller, it was aired by the BBC in April 1976 under the title "Agaton Sax", with actor Peter Hawkins—a well known BBC performer—voicing the characters. All of these changes—namely, the 4-year delay in transmission, the removal of the original title, and the substitution of Peter Hawkins for Kenneth Williams—were designed to conceal as best as possible the fact that the production was simply a remake of the 1972 "Jackanory" serial which had been based on the same book.
