Jackson will play Dale, a gay rights activist, playwright, and author. He was also one of the founding members of the Mattachine Society — one of the earliest gay rights groups in the US — in the early 1950s.

Rapp will step into the role of Harry — another founding member of the Mattachine Society — who scribed the 1948 manifesto "The Call," which encouraged more protection and rights for the gay community.

Purser and Matarazzo are portraying lesbian couple Del and Phyllis. The duo founded San Francisco's Daughters of Bilitis in 1955 — making it the first social and political organisation for lesbians in the US — and published The Ladder, the first nationally distributed lesbian publication in the US. In 2004, they became the first gay couple to wed in the Bay Area. Although their union was later voided by the courts, they tied the knot again in 2008 when the Supreme Court legalized same-sex marriage.

Gilbert's character J.M. is an anonymous reader of Phyllis and Del's publication The Ladder as she is forced to keep her sexuality a secret.

Ramsay's role as an FBI agent will show how the government kept active files on the Mattachine Society and the Daughters of Bilitis as gay rights groups were often considered to be communist and dangerous.

Grey will transform into Lucy, who was a prominent socialite, chef, and prohibition-era entrepreneur, as well as one of the first documented Black transgender persons in the US.

Germaine is set to depict Jack, a Montana resident who spends time in and out of jail while making headlines for refusing to wear gender-conforming clothes.

She became a distinguished nightclub entertainer, author, and lecturer, using her celebrity status to advance the cause of transgender rights.

Wiley will depict Hansberry, the famed A Raisin in the Sun author and civil rights leader who discussed her lesbian identity and gay oppression under various pseudonyms.

Lonsdale's character Bayard was a leading voice in the civil and gay rights movements. He was a close mentor and advisor to Dr. Martin Luther King Jr., helped organise the 1963 March on Washington, and was posthumously awarded the Presidential Medal of Freedom by President Barack Obama in 2013.

Rodriguez is transforming into gay rights icon José, a drag performer who became the first openly gay candidate for public office in the United States, running for a seat on the SF Board of Supervisors. José also founded the Imperial Court System, one of the oldest and largest LGBTQ+ organisations in the world.

Pancake will take on the role of LGBTQ+ rights activist and Mattachine Society president Dick, who was the first gay reporter to publish an account of the Stonewall Riots. The article appeared in a special edition of the Mattachine Newsletter the day after he witnessed the first night of the demonstrations.
