And that people really feel that they knew her or that they feel this protectiveness toward her."At the time of Wood's passing, Natasha was only 11 years old. Over forty years later, she finally got the courage to speak openly about the tragedy.Natasha also co-produced the documentary, Natalie Wood: What Remains Behind, in 2016. In her conversation with the outlet, she confessed:"If someone had told me that I'd be doing this 10 years ago, I would've laughed because I so wanted to forge a path that was separate from my mom. But I think I surrendered to whatever the universe had in store for me."
