I saw this one with Bobbie and I recall we both found it very powerful, although a bit long for its relatively slight story.
What fine acting. Antony Sher & Malcolm Storrey in particular, but a fine supporting cast and Terry Hands directing.
The Theatricalia entry for this one can be found here.
Nicholas de Jongh gave it a good but not ecstatic review in The Guardian:
