Ottman has a tin ear. The extent to which I am a Star Trek music weenie is the same extent to which his failure to discern Goldsmith's recurring Spock motif in STTMP irritates me.
He also has a cameo role in the film (X-Men: Apocalypse).
I'll look for him. Going again this week.
It's a case of blink-and-you'll-miss-him... he's quite prominently featured in-frame, though (IIRC he's in one of the scenes where the missiles are launching - credited as 'Confused Tech').
