I sat through the digital click track performance and I hear it less.  But when you are practicing the 2nd, 3rd or 4th violin parts the sound is much more reminiscent.  Especially there is a little 1/32 note run in there that has that same quality, along with some other fast accompanying runs.

Those movie themes are pretty stark.  I don't think there is any violin in any of them.  But if there was I think there would be a similarity.  There is also the key and mode of HOTRS itself which might be close or the same.
