Saw her last night in Sunday Bloody Sunday - 1971, I think. Bisexual love triangle among the Observer reading classes of Hampstead. She and Peter Finch very good as two points of the triangle, Murray Head plays the obnoxious twat who uses both of them.
A relic of the days when academics could afford huge fuck-off houses, and sire vast broods of ill-mannered and badly-behaved children.
But Glenda J. really was as good as everyone says she was in this one. A quite visually inventive film as well.
It's on YouTube, if anyone's interested.
