I have solved all the clues, I understand both the theme and the silver box. I can't see how to obey the title while leaving real words. I see that if we remove the letters as instructed by the title we have a jumble of the protagonist in row 5 but we also have many non-words. Is the answer to ignore the title? I think not.
Surely for any good puzzle you will know when you have solved it? Here I do not think I have.
