Lady Gaga "Had Some Psychological Difficulty" Filming 'House of Gucci'

It's almost time for everyone to get the murderous fashion epic that they've been waiting for: Lady Gaga and her House of Gucci character, Patrizia Reggiani, are about to hit theaters at the end of the month, giving everyone something to truly be thankful for. In a new interview, however, Gaga noted that during production, she started to lose herself and the line between Reggiani and Gaga started to get blurry. It's a truly intense comment coming from someone whose shown audiences what she can do with A Star Is Born and American Horror Story.

"I had some psychological difficulty at one point towards the end of filming," she told British Vogue. "I was either in my hotel room, living and speaking as Reggiani, or I was on set, living and speaking as her. I remember I went out into Italy one day with a hat on to take a walk. I hadn't taken a walk in about two months and I panicked. I thought I was on a movie set."

Gaga went on to say that prep for the movie took over a year and a half and filming went on ever longer, so she was in character for nearly three years, speaking with that accent, using those mannerisms, and doing her best not to break character, even when the cameras weren't on her. It got so heavy, she noted, that she changes, like her hair color, influenced how she could and couldn't act.

"I will be fully honest and transparent: I lived as her for a year and a half. And I spoke with an accent for nine months of that," she said. "Off camera, I never broke. I stayed with her. It was nearly impossible for me to speak in the accent as a blonde. I instantly had to dye my hair, and I started to live in a way whereby anything that I looked at, anything that I touched, I started to take notice of where and when I could see money."

Gaga also told The Wall Street Journal that her close relationship with Tony Bennett also influenced her portrayal, saying that she wanted to be sensitive to his background and not create a cartoon character.

"I knew I was about to play a murderer. I also knew how Tony feels about Italians being represented in film in terms of crime. I wanted to make a real person out of Patrizia, not a caricature," she said. "I felt the best way to honor Maurizio [Gucci, played by Adam Driver] and Italians was for my performance to be authentic, from the perspective of a woman. Not an Italian-American woman, but an Italian woman."
