I have nearly everything: the two messages, the film, the names of three characters - but I cannot parse 33d.
If I am correct in my answer, I have a constructed clue which I cannot solve, even though I know the theme and the three characters.
Do the 'initial letters' (in the second sentence of the preamble) refer to the clues or to the redundant words? Either way, they do not suggest anything to write below the grid.
