Wonderful actress!

Just watching The Man in the Sky 1957, made the year I was born and looking a bit dated, like me. There are some good performances in the film, Jack Hawkins in the lead role and some notable character support from Megs Jenkins and John Stratton to name but two. But for me it is Elizabeth Sellars who has the stand out role as the supportive wife, she makes what could be simpering part into an emotional tour de force. I understand this wonderful actress is still with us in her nineties! I will certainly be seeking out more of her performances, has anyone got any recommendations?
