Angelina Jolie's biopic "Maria," about American-Greek opera singer Maria Callas, was released in theaters Nov. 27 and is now streaming on Netflix. One of the big questions surrounding the film is whether or not Jolie actually sings -- and it turns out the answer is yes,

Callas, known as “La Divina” (The Divine), was an American-born Greek soprano who rose to fame in the 1950s and is often credited with the bel canto revival. She is considered one of the most renowned and influential opera singers of the 20th century and one of the greatest divas of all time due to both her talent and her temperamental reputation.

Angelina Jolie really is singing opera in Maria, but it’s not only Jolie’s voice in the final product. The movie blended Jolie’s singing voice with recordings of the real Maria Callas, so the result is a hybrid of both Jolie and Callas’s voice.

Netflix's "Maria," starring Angelina Jolie, imagines opera singer Maria Callas' last days. The true story of her life was of abuse, drugs, and health issues.

La Divina boutique hotel, in Athens, is inspired by Maria Callas — and every suite is named for an opera she performed.

Angelina Jolie plays Maria Callas as the opera star re-examines her life in her final days in Pablo Larrain's Netflix biopic "Maria."

The diva in question is not Maria Callas, the famous and revered opera singer whose scandals were as dramatic as her performances. The diva I’m talking about is Angelina Jolie, who plays Callas under the direction of Pablo Larrain. Jolie’s performance is all over the place because the director and editor cut it that way.

Throughout the film, there are many closeups of Jolie-as-Maria performing, leading viewers to wonder: Is Angelina Jolie really singing in Maria, or is she lip syncing to Maria Callas recordings? It's a mix of both.

Angelina Jolie at least brings passion to Pablo Larraín's Netflix Maria Callas biopic "Maria," a far cry from the brilliant "Jackie" and "Spencer."
