This was a movie from the late 70s or early 80s, and I believe it was reviewed by Siskel & Ebert.
All I can really remember is one scene in which a commando/spy character –like a James Bond–is skiing down a mountain evading people (Soviets?) trying to kill him. At one point he hits a jump which takes him over the ski lodge’s deck (where incredibly people are still dining during this gunfight, if I recall) and does a mid air spin, shooting his pursuers –also in the air–with a MAC 10 or Uzi.
For the longest time I thought it was called The Specialist (not the 1994 movie) but I have not been able to find that title online anywhere. I want to say this predates the Arnold and Stallone movies and it seemed to be in the spirit of a James Bond movie.
