With all of the Star Wars: The Force Awakens hype going on, I remembered that, as a kid, I thought I heard WWV in a scene from The Empire Strikes Back.
I looked through some video clips of the movie online and discovered it again this morning: I heard the WWV-like sound in the Battle Of Hoth scene. [Update: RadioGeek suggests this may actually be CHU’s date pips.]
This video clip will start around the :23 second mark; start listening for the metronomic tick in the background around :25 seconds and then again at :40 seconds:

I may be mistaken, but I believe that sounds like 1980s era WWV. Has anyone else noticed this?
