The Slavers

Shot in 1977, director Larry Kent lost control of the film because of money he owed, and subsequently the film was completed and released in 1984 without his involvement. Apparently the most significant changes lay in the dialogue and with the voices. The film was shot silent, everything was post-dubbed so it was easy to make the changes. Kent estimates that about 80% of the dialogue has been changed, and that the voices of characters like the Professor and his assistant are not those he would have chosen.
