Matt Bomer is remembering his late friend Larry Kramer.

The 42-year-old actor took to Instagram on Wednesday (May 27) to pay tribute to the AIDS activist who wrote Broadway’s The Normal Heart after his death at 84.

“Larry Kramer. I don’t have the words to properly express my gratitude, admiration, and love for you,” Matt wrote. “Your writing was bold, courageous, and urgent. It educated, stirred people to action, and saved lives. A towering intellect and an amazing wit. My time with you is something I will treasure for the rest of my life. Rest In Peace my friend.”

If you didn’t know, Matt and Mark Ruffalo starred in the 2014 film adaption of The Normal Heart on HBO.

Larry Kramer, an Oscar-nominated screenwriter, playwright, author, gay rights and AIDS activist who wrote Broadway’s The Normal Heart, has tragically passed away at the age of 84.

He passed away on Wednesday (May 27) in Manhattan of pneumonia, his husband David Webster confirmed to the New York Times.

Larry was best known for The Normal Heart, which chronicled 1981-84 during the AIDS crisis. In 2011, the Normal Heart won the Tony Award for Best Revival of a Play. In 2013, he won a special Tony Award for his contribution to humanitarian causes. He was nominated for an Academy Award for Writing Adapted Screenplay for Women in Love in 1970.

He also founded the AIDS Coalition to Unleash Power (ACT UP) in 1987 to fight against AIDS. He himself contracted HIV in the late 1980s.

RIP.
