"The Poppy Fields" plays during the main titles of The Shadow, providing its mysterious theme right off the bat.  I remember immediately liking the score as soon as I heard it when I watched the movie for the first time.  It's too bad there's not a good way to replicate the eerie pitch slides on the piano, but it's still fun to play nonetheless.

Jerry Goldsmith is one of my favorite composers, and I love the mysterious themes he uses in the soundtrack of The Shadow.  "The Hotel" is one of those songs that has a lot of parts that are fun to play, especially when the main theme is heard.
