Jane Fonda was considering using her 1972 Oscar acceptance speech as a platform to slam America's ongoing participation in the Vietnam War, until her late father PETER persuaded her it wouldn't be a good idea.

Jane, who was honoured with a Best Actress Academy Award for her role in 1971's Klute, changed her mind when her legendary dad suggested she would be wiser to leave politics alone that night.

Jane says, "I thought I was going to win. I'd been nominated before (for THEY SHOOT HORSES, DON'T THEY?) and didn't think I would, but this time I thought I was going to win and I thought, 'Should I say something about the war?'

"I mean, what an opportunity. There's hundreds of millions of people watching the Academy Awards. Would it be irresponsible if I didn't?

"And I asked my dad for advice and he said, 'Why don't you just say that there's a lot to be said but tonight isn't the time?' And that's what I said and it was the perfect thing."
