The Waltons' Ellen Corby was an expert at playing old ladies

When you needed an old lady, you called Ellen Corby.

While she was well known for playing Grandma Walton in The Waltons, Ellen Corby had an incredibly illustrious career as an actress in both film and TV before she joined the cast of the hit series.

Although Corby had appeared in various television programs and films, she tended to have a type when it came to her characters.

"Even when I was young, I was playing old people," Corby said in an interview with the San Francisco Examiner. "Just the way I looked, I guess. You fill a need, and soon everyone is using you. Never was the heroine, though. Always the older woman giving advice, consoling another, raising the children. Just like Grandma Esther."

Like any good actor, Corby did her due diligence in ensuring that she understood Grandma Esther. Despite her experience playing elderly characters, no two old ladies are exactly alike.

"She sees no humor in anything," Corby said. "And, of course, this makes it harder for me to find the comic side within her. She was a frontiers-woman fifty years before, and hard as nails."

But while the comedy of The Waltons was difficult to find at times, that doesn't mean that it didn't exist, according to Corby.

"I think Grandma has her human side, her comedy side, which does come across," Corby said. "So do all the Walton characters. It's what makes the series so meaningful to me."
