The Witches star was at a loss after sculptor Robert Graham died and she admits she was tempted to while away her time behind closed doors.
But Huston, 60, decided to throw herself into her work and snapped up the chance to star as a theatre producer on forthcoming drama Smash, a behind-the-scenes look at the making of a Broadway musical.
She tells W magazine, ""A few years ago, a TV show might have been unthinkable to me. But now, as a single person, I don't want to just sit in our house regretting what's passed. This feels like I'm embarking on a new chapter.""
And Huston admits the role was perfect for her advancing age.
She says, ""Television is where the great parts are for women my age. But I begged the writer to make my journey a pleasant one - since my life generally reflects my art.""
