Meryl Streep was nominated for two Golden Globes Wednesday morning – one for best dramatic actress for "Doubt" and for musical or comedy actress for "Mamma Mia!"

(By the way, actress Kate Winslet also had two nominations: best dramatic actress for "Revolutionary Road" and supporting actress for "The Reader.")

But before taking the "Doubt" role as Sister Aloysius Beauvier – the strict Bronx Catholic school principal who suspects a priest (Philip Seymour Hoffman) of having inappropriate relationships with young boys – CNN reports that Streep admits she had some second thoughts about this role. But she changed her mind once she saw the final product. The film also features Amy Adams and Viola Davis.

From CNN:

"I actually didn’t think it would ever be a movie," Streep said. "It was so thoroughly realized on stage, and it was so minimal. It was hard to imagine how or why you would make a movie out of it."

"How did they make the play without any children in it? It is just sort of amazing to me, because to me they are sort of the landscape. They are the lambs of the movie. They are the stakes. They are why everybody is passionate."

Streep also tells Parade that she still gets insecure when taking on a new role. Really? We never would have guessed! So what was it like to play an uptight, cranky nun?

I felt sort of like I did when I was playing the boss from hell in "The Devil Wears Prada." The rest of the cast was hanging out and having fun, but I was sort of lurking on the sidelines, waiting for my next scene in which I’d be making somebody feel horrible. I overcompensated at home after a day of being mean on the set by being extra nice to my husband. I got all my nasty rocks off at work, so I was like, "Can I do anything for you darling?" I was sweeter than melted butter.  

"Doubt" also scored supporting Golden Globe nominations for Hoffman, Adams (as Sister James) and Davis (who plays the mom of a student involved in the sex-abuse allegations), plus a screenplay slot for director John Patrick Shanley, who won a Pulitzer Prize for the theater version.

Apparently Streep thinks highly of her co-actress Davis’s performance. She advised Davis to pick out a dress for the Academy Awards; nominations will be announced January 22. The awards ceremony is scheduled for February 22.
