At least two BC-191/375s made it into the movies....

In the classic John Wayne "Island In The Sky", it's the main
transmitter in a transport plane downed in the snowy reaches of
northern Canada during WW2. You also see a BC-348 and a Gibson Girl in
action.

In the original "Manchurian Candidate", during the climactic scenes
where Laurence Harvey goes to the unused spotlight room during the
convention, there's a BC-191/375 used as a prop in the room. No
connection to the story at all. The set dresser probably thought it
looked enough like PA equipment to pass muster.

The original "Flight of the Phoenix" shows an ART-13 but it is not
used in the story.
