Re: Howard Shore title card, if I remember correctly, this occurred with trailers from either "The Mask of Zorro" or "Mighty Joe Young", on television, following the success of "Titanic". I remember this being discussed at the then World Wide James Horner Shrine.
I don't remember the TV spots for those Horner films, but given the colossal success of Titanic's song and score that makes sense.
I think for Nightbreed, Danny Elfman's credit was isolated in a large "box" in either trailers or TV spots, presumably to capitalize on the success of Batman.
