8 major moments from Prince Charles and Princess Diana's marriage that 'The Crown' didn't show

In episode three, "Fairytale," viewers watch as Princess Diana (played by Emma Corrin) gets into her wedding gown and the rest of the royal family prepares for the big day. But the credits roll just before the wedding begins, skipping the major event completely.

"We never re-create things just for the sake of re-creating them," Corrin told The Hollywood Reporter. "The wedding scene, you can YouTube it and you could be watching it in 10 seconds so I don't think there'd be any point in us re-creating it."

The real royal wedding took place on July 29, 1981. Diana wore a $110,000 wedding gown made by David and Elizabeth Emanuel — it was a heavily "guarded secret" up until the wedding day. The royal pair tied the knot at St Paul's Cathedral because it had more seating than Westminster Abbey, according to Time. This move to the larger venue foreshadowed the huge interest in the royal wedding. In fact, it became one of the most-watched events in TV history, garnering 750 million views, according to the BBC.

Princess Diana remembered the day as anything but a fairytale. "I don't think I was happy. I never tried to call it off, in the sense of really doing that, but I think [it was] the worst day of my life," she said in "Diana: In Her Own Words."

Season four has many scenes with Princess Diana bingeing and purging food, but her state of mind during this time period was even more complicated.

In 1991, Princess Diana secretly met with a friend to record an interview for Andrew Morton, who was writing a biography of her royal life titled "Diana: Her True Story." During the interview, she talked candidly about the same time period featured in season four of "The Crown."

In the interview, Diana talked about her depression in the early stages of her marriage with Prince Charles. She also said she self-harmed and attempted suicide five times.

"When no one listens to you, or you feel no one's listening to you, all sorts of things start to happen," she said in her controversial 1995 interview with BBC's Martin Bashir. "For instance, you have so much pain inside yourself that you try and hurt yourself on the outside because you want help, but it's the wrong help you're asking for."

The princess also revealed she had postpartum depression after giving birth to Prince William.

In the same 1991 interview for Morton, Princess Diana said she threw herself down the stairs.

"When I was four months pregnant with William I threw myself downstairs, trying to get my husband's attention, for him to listen to me," Diana said in the taped video, which can also be heard in the documentary "Diana: In Her Own Words." "I had told Charles I felt so desperate and I was crying my eyes out. He said I was crying wolf. 'I'm not going to listen,' he said. 'You're always doing this to me. I'm going riding now.' So I threw myself down the stairs. The Queen comes out, absolutely horrified, shaking — she was so frightened."

Diana said she was bruised around the stomach, but the baby was fine.

In 1989, Princess Diana went with Prince Charles to the birthday party of Camilla's sister, even though Charles didn't want Diana to come, according to the taped interview from 1991.

During the party, Diana noticed Camilla and Charles were nowhere to be found, so she went looking for them. She learned that they were downstairs talking to another man. Diana said she sat down with them and interrupted their conversation.

"I said, 'Camilla, I'd love to have a word with you, if possible,'" Princess Diana said in the 1991 interview. Camilla looked uncomfortable but agreed, she said.

Diana told the men she was going to speak with Camilla: "They shot upstairs like chickens with no heads and I could feel, upstairs, all hell breaking loose. 'What is she going to do?'"

Once pulled aside, Diana said, "'Camilla, I would just like you to know that I know exactly what's going on.' She said 'I don't know what you're talking about.' I said 'I know what's going on between you and Charles, and I just want you to know that.'"

According to Diana, Camilla responded by saying, "'You've got everything you've ever wanted. You've got all the men in the world falling in love with you, you've got two beautiful children, what more do you want?'"

"I want my husband," Diana said back.

On the way home, Diana said she "cried like I have never cried before."

In season four of "The Crown," there were many scenes where Prince Charles and Camilla (played by Emerald Fennell) chatted on the phone, but the creators kept one specific phone call out of the series.

In 1989, a raunchy phone call between the pair was recorded. In it, the prince jokes he'll "live inside your trousers," and that he'll come back as a tampon.

The phone call was leaked in 1993 and was given the name "Tampongate." The incident is so well-known that Josh O'Connor who plays Prince Charles in the series said he demanded to not have the scene in the show.

"When they offered me the role," O'Connor told Sirius XM, "one of my first questions was — I say questions, I think it was pretty much a statement — 'We are not doing the tampon phone call.'"

Even though "The Crown" skipped over the pregnancy and birth of Prince Harry, it was a major turning point in the royals' marriage.

Before Harry was born on September 15, 1984, Princess Diana said it was a very happy time in her marriage in "Diana: Her True Story."

"Charles and I were very, very close to each other the six weeks before Harry was born, the closest we've ever, ever been and ever will be," she said.

However, she also said that Charles wanted a girl, so when Harry was born, their marriage took a turn.

"Then, suddenly, as Harry was born, it just went bang, our marriage," the Princess of Wales said. "The whole thing went down the drain."

In the fourth season, Princess Anne (played by Erin Doherty) tells the Queen (played by Olivia Colman) that Diana is having affairs with many men. The series briefly shows her relationship with a man named Major James Hewitt, but it does not dive into any of the details.

Reportedly, the affair lasted five years between 1986 and 1991. They met at a cocktail party where Diana asked him to give her riding lessons. "The Crown" shows the princess sneaking him into Kensington Palace, but she also brought him to Highgrove, Prince Charles' private residence, when he was away. When their relationship ended in the '90s, Hewitt published a tell-all book, "Princess In Love," about his affair with the princess.

"Yes, I adored him. Yes, I was in love with him. But I was very let down," Diana told the BBC in 1995.

Season three of "The Crown" features the making of a documentary that the royals made in 1969 titled "Royal Family." Princess Diana and Prince Charles made their own documentary during their marriage, but it wasn't featured in the series.

In "Diana: In Her Own Words," the princess said she initially didn't want to participate but eventually agreed to when the network said they would donate money to the Charities Trust.

In one scene, a young Prince Harry and Prince William are seen playing around on a piano. In another, the journalist asks Diana: "What do you say when you read in the papers that you are a determined, domineering woman?"

"I don't always read that," Diana responded. "People are very willing to tell me that, but I don't think I am. I'm a perfectionist with myself, but not necessarily with everybody else ... I don't think that I am ... There's far too much about me in the newspapers. It horrifies me."

The princess also said in the interview that she and Prince Charles rarely fought.
