Edie Falco "couldn't stop crying" during the script read-through for 'The Sopranos' finale

She said during a retrospective film about the show for CBS News: "I was out of control. I was embarrassed.

"I really couldn't stop crying - it was ridiculous. It was, 'This thing in this moment will never happen again to me, to anyone.'"

The series finale is infamous for cutting to black as its lead character Tony Soprano - played by the late James Gandolfini - looks up at a door opening in a diner, leaving fans furious and puzzled over whether it meant he had been assassinated by a mob rival.

When told during the CBS look-back at the series that it probably changed many people's lives, Edie agreed by saying: "I think all of ours, in all kinds of ways."

The actress also said she had a "alchemy" with her co-star James, who was killed by a heart attack aged 51 in 2013.

Mother-of-two Edie, who has never married, added: "We both had Italian families, had some idea of what this dynamic feels like, and just sort of fell into it with great ease.

"It was, you know, a 10-year marriage. And it was as close to a real one as I had known."

Edie won three Emmys and two Golden Globe awards for playing Carmela.

Even though she says she loved shooting it, she has said her adopted children - son Anderson and daughter Macy - have never seen 'The Sopranos'.

She previously told People: "They're so over it. They've never seen it. Either of them.

"But I hope that maybe someday they will and maybe they'll like it. But yeah, they're not impressed at all."
