The Story of a Woman (John Williams) The Amazing Mr. Blunden (Elmer Bernstein) Endless Night (Bernard Herrmann) Now, Voyager (Max Steiner) Forever Mine (Angelo Badalamenti)
I usually say "anything unreleased by John Williams, Danny Elfman and Elliot Goldenthal", but if I were to boil it down to 5 (and limiting it to FILM scores rather than concert works, TV works etc.), I'd say:
STORY OF A WOMAN (John Williams) BATMAN & ROBIN (Elliot Goldenthal) HOT TO TROT (Danny Elfman) ROMEO & JULIET (James Horner) ....and right now, GHOST IN THE SHELL (Lorne Balfe & Clint Mansell)
Twice Upon a Time (Dawn Atkinson and Ken Melville) Modern Problems (Dominic Frontiere) Troy (Gabriel Yared) The Sunbow/Marvel Collection (Johnny Douglas and Rob Walsh) The Big Red One (Dana Kaproff)
Fright Night Part II - Brad Fiedel Psycho III - Carter Burwell Airport '77 - John Cacavas Batman & Robin - Elliot Goldenthal King Kong (rejected) - Howard Shore
