Screen Test II by Tilsit

Clues are normal, but need to be entered into the grid with a misprinted letter always occurring at an intersection with another answer. Taken in sequence, the misprinted letters reveal the names of two actresses who starred in different versions of the same film. Eight answers are clued by definition-only clues (in no particular order), and need to be treated before entry to the grid, where they should be fitted jigsaw-fashion.

The title of this film shows how the eight answers are to be treated before entry and should be written in the space provided. Finally, solvers must make an amendment to one of the rows of the completed grid in line with the theme. Chambers Dictionary (2003) is the primary reference, although solvers may need internet aid to identify the film..
