Hannay

Hannay was a program spun off from the 1978 film The 39 Steps which was the 3rd film adaptation of the 1915 John Buchan novel (the first one was the Alfred Hitchcock masterpiece of 1935). The time-period is 1914 so it's a little surprisng to see star Robert Powell with a very 1980's perm. We expect that stuff from Hollywood, but not in a British period work.
