A new biography of Marlon Brando, written by Darwin Porter, has recently been published.

The book, titled ‘Brandon Unzipped’, reveals that the actor had homosexual relationships with some of his co-stars and directors.

In the book, Porter alleges that Brando had s**ual encounters with James Dean, Cary Grant, Montgomery Clift, and Sir John Gielgud.

According to Porter, Brando’s relationship with James Dean was one of his most enduring yet tumultuous affairs.

He claims that they had a relationship for several years, but it was always fraught with tension.

Porter goes on to say that their relationship reached a boiling point at a party in Santa Monica, California, where they had a big fight witnessed by dozens of people.

Porter also alleges that Brando had a long-term romantic relationship with Montgomery Clift.

“His affair with Montgomery Clift was a long and enduring relationship,” writes Porter in the book.

Additionally, Brando allegedly had a fling with Cary Grant, spending a weekend with him in San Francisco.

Porter claims that Grant was also pursuing actor Stewart Granger, who became another of Brando’s conquests.

However, Porter clarifies that Brando had a different kind of relationship with Sir John Gielgud.

“Marlon admired John Gielgud, but they didn’t have a relationship,” explains Porter.

“Rather, Brando performed s**ual favours for Gielgud and told friends, ‘I owed it to him because he really helped me with lines in Julius Caesar.'”

Brando expressed his homosexuality in his own 1976 autobiography, stating: “Like a large number of men, I, too, have had homosexual experiences, and I am not ashamed.” However, despite his openness about his sexuality, Brando was married three times during his life.

He died of lung disease at the age of 80 in July 2004.

Porter’s book has caused controversy among fans of Marlon Brando, who feel that the revelations about his personal life are unnecessary and intrusive.

However, Porter defends his decision to include these details in the biography, stating that he wanted to show a different side of the actor that had not been explored before.

“Marlon Brando was one of the most talented actors of his generation, but he was also a complex and multifaceted individual,” explains Porter.

“I wanted to show a side of him that had not been seen before – his relationships with other men, and how they influenced his life and career.”

The book has also raised questions about whether Hollywood is still a homophobic industry, with some commentators suggesting that Brando’s sexuality may have impacted his career.

However, others argue that Brando’s talent and star power were enough to overcome any prejudices that may have existed.

Despite the controversy, ‘Brandon Unzipped’ has become a bestseller, with many readers curious to learn more about Marlon Brando’s personal life.
