Actress Cate Blanchett says she first watched a sex scene when she was in the third grade and her parents took her to see the risque 1976 film 'Silver Streak'.
"I remember the first time I saw a sex scene. My parents took me, I think I was (in) the third grade. It had Gene Wilder in it, and it was Silver Streak," Blanchett told a magazine.
"There was a sequence in it but he's on a runaway train, so you think it's going to be funny and we can take the kids to that, but he was with this woman on a train, running from the law, and he'd hurt himself. She started to kiss him.
And he said, 'Well actually it hurts here and here' and I thought, 'Where is this going?' And she started to unbutton his shirt.
I could feel my mother's buttocks clenching beside me. And I thought, 'Ooo I want some of that'," she added.
