Puzzle 58 - 15x15 themeless

I love seeing full names in grids. This puzzle has three, all of 8 letters. And besides the two grid-spanners, they're the puzzle's most intentional entries. I think the crossings are fairish. Or inferable. I decided to give one anagram hint just in case.

Oh by the way I came up with this other thing (though "discovered" seems more apt a word). I'm going to try to write it in the style of the Brain Tickler in the print New York Times.

            Take each letter once from the phrase HORROR/THRILLER to form the name of a film director (3,4).
