Star Trek II: The Wrath of Khan Easter Egg - Composer Cameo

During the short scene when we see the Enterprise crew preparing for battle around the ship as it leaves Regula I, score composer James Horner can be seen walking down a corridor in a cadet uniform.

It comes just after the full-screen red alert graphic, with two guys walking towards the camera down, the RIGHT side of the corridor, holding torch-like objects. The first man is Horner.

Director Nick Meyer admitted this one in his director's edition commentary.
