For anyone stuck at home today like me you may wish to tune in to channel 41, the Great Movies Action channel, at 4:30. They are showing Von Ryans Express a WWII film featuring Frank Sinatra much of which was filmed in El Chorro and gives some fleeting glimpses of the Kings Way and the surrounding cliffs.
On a similar theme it is worth noting that the film "The Heroes of Telemark" shows a lot of the ice falls around Rjukan which is the area where the both the real life events and filming took place.
