Meryl Streep is regarded by many movie buffs to be one of the best actresses that has ever graced the silver screen — and the Hollywood legend attributes most of that success to not caring about how attractive she is.

The 60-year-old says she is successful because she invests her full interest in performing without much regard for how she looks.

“I can’t remember the last time I really worried about being appealing,” Streep reveals in the January issue of Vanity Fair. The latest edition of the Couture Bible will feature photos of the actress dating back to the late 1970s. Some of the snaps include those taken by Brigitte Lacombe in 1979.

The actress forging new ground in the upcoming romantic comedy It’s Complicated, alongside Alec Baldwin and Steve Martin.

“I’ve been given great, weird, interesting parts well past my ‘Sell by’ date,” she says. “I remember saying to Don [Gummer, Meryl’s husband] when I was 38, ‘Well, it’s over.’ And then we kicked the can down the road a little further.”
