Matthew Perry Was ‘Fountain of Light’ Says “Studio 60 on the Sunset Strip” Costar Bradley Whitford

Perry — who died Saturday at the age of 54 — played Matt Albie on the NBC show

Matthew Perry is being remembered by his former costar Bradley Whitford.

On Tuesday, Whitford, 64 — who played Danny Tripp in Studio 60 on the Sunset Strip alongside Perry’s Matt Albie from 2006 to 2007 — penned a sweet tribute to his late castmate, who died on Saturday at the age of 54.

“Matthew Perry made me laugh. Hard,” Whitford wrote in his caption as he shared a throwback video of the pair joking around together during a press interview for their NBC show.

“You have not lived until you have witnessed one of his in-between-the-takes confidential riffs on the absurdity of show business and the idiocy of male confidence," he added, "wrapped up perfectly with the sudden realization that we were both grown men who wear makeup for a living."

Whitford then added that Perry “had a huge, open heart and a pyrotechnical, joyous brain,” and that the actor’s “most beautiful parts” made him “the most vulnerable to the monster that he would have to fight for the rest of his life.”

He went on to describe Perry’s struggles with addiction as “heroic,” adding "They don’t have award shows for that. They should."

"Matt was full of contradictions," he continued. "He was hilariously self deprecating and insecure and wildly self confident. He was a fountain of light with a huge capacity for darkness. He was profoundly blessed and terribly cursed.

"I want his parents to know that Matt was kind. Not just to his costar. To everyone."

The Handmaid's Tale star continued that people should continue Perry’s work by opening their hearts so others “who share his vulnerabilities” can be encouraged to seek help and receive support.

“I’m so grateful that I had the opportunity to work with Matt, to spend some precious time with him, and most of all, to be his friend,” Whitford wrote as he finished his post.
