Michael Giacchino interview

Not a lot to it, but it's pretty much the textbook answer you would expect from a film composer. I wouldn't fear whether or not he'll be using the old themes, I'm fairly sure we'll hear them in the film.

I agree  with GMAN

I just know him for his work in the incredibles and cloverfield, and they both have an amazing soundtrack.

this movie may or may not suck (I hope not), but im sure that the OST will be epic.

Peace!
