Trying to identify a movie from the 70s or 80s.  Color, English language.  I thought Vincent Spano was in it, but nothing in his filmography seems to fit.

I can only remember one scene.  It seems like this character (whom I thought was played by Spano) is in some sort of remote research station in a cold, snowy location.  He was watching a screen/monitor on which he could see a younger boy, but he couldn’t hear him or communicate with him.  It seems like the boy was in a separate facility, and there was some element of danger.  Like the man wanted to warn the boy.

That’s all I can remember.  I think it was a movie that was played on a seemingly endless on HBO back in the day.  Thanks for any suggestions you all may have!
