The 67-year-old actress' biggest concern was that she wouldn't be cast in any more movies, but she is proud she still boasts a successful career 27 years later, reported Femalefirst.
"I remember as I was hovering around 40, I thought each movie would be my last, really. And all the evidence of other 40-year-old women at that time - this is 27 years ago - would lead you to believe it was over," Streep said.
The Oscar-winning star said she would have been "unhappy" if her acting career had of come to an end because of her age.
