Actress, filmmaker and activist Angelina Jolie said people should know better than to fall for the "old tricks" of populist leaders.
Jolie was speaking in Cambodia to promote her Pol Pot-era film "First They Killed My Father".
Jolie was asked to comment on the dangers of rising populism during a BBC interview published on Monday.
"This is an old trick and we should know better [than] to fall for it," the director said, The Washington Post reported.
"And I see it rising, and the only thing I can do is use my voice and encourage others. And raise my children to know right and wrong and to have a broader view of the world and to embrace their diversity and other people's, and respect others.
"And I think that's all we can do right now, is each and every person - each one of your listeners - we all just have to be the best of ourselves," she added.
"Now more than ever, we really have to rise up and find our rational center, our who-we-are and what-do-we-stand-for. And we know it. We know what's right and wrong."
Jolie didn't mention a particular country or politician in her remarks on populism.
The Oscar-winning actress wrote an op-ed earlier this month for The New York Times criticizing President Trump's travel ban and calling on the US to respond to terrorism with facts instead of fear.
