Meryl Streep wants to play Hillary Clinton in a movie

She said: "I'm very flattered to hear that [Hillary wants me in a biopic] but I'll have to wait for that role. All her great achievements are ahead of her.

"This election cannot come soon enough. We've been very burdened by it."

Meryl has previously shown off her vocal skills in 'Into the Woods' and 'Mama Mia!' and admitted she harbours a secret ambition to be a singer.

Speaking at a press conference at the 2016 Tokyo International Film Festival, she said: "I would still like to be a singer. I'm not very good. But I keep trying."

In her latest film, 'Florence Foster Jenkins', the Oscar-winning actress portrays an heiress with a dream of being an opera diva, despite not being a particularly good singer, and Meryl had fun with learning the songs properly - and then "screwing around" with the tracks.

She said: "I did try to learn how to sing these arias properly. I had a great opera coach who taught me properly. Then for the last two weeks, how shall I put it, we screwed around with them."

Meryl thinks movies such as 'Florence Foster Jenkins' and 'Mamma Mia!' proves Hollywood is changing as there are increasingly more good roles available for older women.

However, she does still think "ageism" is a problem.

She said: "I don't think there's ever been a film in American film history that had as its leading person a 70-year-old character. So I was playing someone much older than myself. And somehow, I pulled it off.

"Yes, I think there has been ageism and all these so-called market-driven decisions. But I was 58 when I made 'Mamma Mia!' and that was the most popular film I've ever made!

"So I do think all these rules are being broken - and thank goodness! I think a lot of it is the fact that there are a lot more opportunities driven by television, especially the long-form narrative and serial television that we have now. It has been very good for women and proves that there has been an audience."
