Michelle Pfeiffer, 68, reveals very harsh conditions while filming The Madison after initial tension with Taylor Sheridan

Michelle Pfeiffer really had to rough it when filming Taylor Sheridan's The Madison in Montana.

The 68-year-old Hollywood icon told the Los Angeles Times podcast, In Conversation: The Madison, that there were zero normal accommodations during the shoot.

One of the worst things about being out in the middle of nowhere for the show - about a wealthy New Yorker who suddenly loses her husband - was the plumbing issues.

There was no toilet, and even the outhouse that is seen in the series was fake so it was not an option, the award-winning actress said. That forced stars to do their business out in the bushes.

'You may as well be in a tent because, you know, there is no bathroom,' Pfeiffer said. 'Even the outhouse is not real. So there's no AC, there's no plumbing, there isn't anything. But it is breathtakingly glorious.'

This comes after Pfeiffer shared that she had tension with Yellowstone creator Sheridan at first after he asked her to sign onto the program without seeing a script. 

Then there was the temperature: it was either too hot, causing Pfeiffer to use an umbrella as there was little shade, and she relied on coats and space heaters when it was cold.

Hollywood stars are known for squirreling away in trailers between scenes, but the beauty did not have that option either as the show was shot in 360 degrees and trailers could not be spied.

Pfeiffer plays Stacy Clyburn on the Paramount+ TV show. She tries to keep the family intact as they struggle with rural Montana after living the high life in New York City.

The spoiled characters spend much of the show complaining about the lack of amenities. 

'It took a while [to get used to] because they built that cabin. It was all a little bit rushed for everyone and so there weren't certain accommodations set up,' she said. 

'We didn't really have trailers there because they were shooting 360 [degrees]. So, they couldn't have a bunch of trailers around.

'There was really no place for us to sit,' she continued. 'There was no bathroom nearby. There was no food. And in the winter, it was cold. It was like, "Could we have a heater?"

'And in the summer, it was like, "Could I get an umbrella because the sun's really intense?" It took us about halfway through to figure all of that out.'

Pfeiffer recently revealed that she agreed to star in The Madison without reading a script for the show. 

The actress took a 'leap of faith' to join the cast because of creator Sheridan's previous involvement in successful shows, such as Yellowstone and Tulsa King.

Michelle told Variety: 'Taylor reached out to me and said he had an idea and would like to meet me.

'So I'm off to Texas, I went to his ranch and had a wonderful evening meeting people. He talked to me about the arc of the character and the concept of the show, and it was very broadly laid out.

'I said, "Okay, when could I read something?" He said, "Well, I'd like to know who I'm writing for before I start writing. So after you commit."'

Pfeiffer called up her good friend Helen Mirren, who had worked on Sheridan's Yellowstone prequel 1923, to vet him. Mirren sang Sheridan's praises so Pfeiffer signed on to The Madison with no script.

The show has already been renewed for a second season.

This comes after Pfeiffer said she has learned many valuable lessons through losing people in her life. On  The Madison, her character experiences intense grief when she loses her husband, played by Kurt Russell.

The actress has 'suffered losing someone who was meaningful' to her more than once in her life, and Michelle admits that the experience has taught her some lessons.

Speaking to Entertainment Weekly, the Hollywood star explained: 'For a brief amount of time, all that really matters is connection with other human beings.

'I remember feeling it a couple of times in my life when I suffered losing someone who was meaningful to me. I remember thinking, "Oh my God, how can I hold on to this?" It felt so good and so real and authentic and safe … 

'And in a weird way, it was relaxing, because I wasn't busy just trying to make things happen. You just stop all that.'

Pfeiffer also admits that it can be hard to think clearly in the midst of heartbreak.

The movie star - who was married to actor Peter Horton between 1981 and 1988 - said: 'When you have grown up with someone and you're so entangled with each other, after a while, you don't really even know where you end and the other person begins.

'How do you even start to imagine your life without them and rebuild when everything you knew has fallen apart?'
