I think she was in a television film called
Hand in Hand. I am sure it was a British film, but made for television. it must have been made in the mid 60s. I'm deliberately not looking it up. I want to see how much I can recall.

All of this is based on a memory from forty years ago. I was about six or seven - it had a great impact on me. It is about a Catholic boy and a Jewish firl who become friends.
For me, it was one of those British films that made me realize how different they were from the homegrown product (home being the US) - films like
Sammy Goes South and
Wee Geordie. I've been hooked ever since.
