Given the all-star cast - a 'name' in almost every role - I was surprised that I'd never heard of this adaptation until accidentally finding it on a repeats tv channel today.
As the film proceeded I quickly realised why this is so. I doubt whether any of the famous actors fondly remember their participation.
Enjoyable though it always is to see York, Mason, Leighton, Miles, Quayle, Ray, Morley, Bull et all, without doubt it is a wooden script they deliver and every other televised or filmed version I've seen over the last fifty years is better than this one.
