Rosanna Arquette is reminiscing about the joy she experienced while working with the late Matthew Perry, who passed away at the age of 54 on Saturday.

Arquette and Perry shared the screen in the 2000 comedy film, The Whole Nine Yards, portraying Nicholas “Oz” Oseransky and Sophie Oseransky, a married couple residing in Montreal who discover that their new neighbor is a hitman from Chicago, played by Bruce Willis.

“He was kind, lovely, funny, and sweet. Working with him was a dream. There was never any negativity, only fun," says Arquette, 64, in an interview with PEOPLE.

She continues, “He had a fondness for grape soda.

He always had a can with him, and he truly enjoyed it. It was quite amusing. He even gave me a can, and I found it to be delicious.”

After completing her scenes for the film, Arquette reveals, “I sent him a large case, a couple of big cases, to last him for a while.”

However, beyond that, she admits, “I didn't see much of him. We bumped into each other a few times at events over the years, and he was always kind and affectionate, but we didn't spend much time together.”

Arquette expresses that Perry’s passing is especially devastating for the cast of Friends, the popular NBC sitcom. Her brother, David Arquette, was married to Courteney Cox, one of the show’s stars, from 1999 to 2013.

“For them, it feels like they lost a brother,” she shares.

In a joint statement exclusively provided to PEOPLE on Monday, Cox, Jennifer Aniston, Matt LeBlanc, Lisa Kudrow, and David Schwimmer conveyed their grief and shock.

“We are completely devastated by the loss of Matthew. We were more than just co-stars, we were a family,” the statement reads. “There are no words to adequately express our feelings, so right now we will take a moment to mourn and process this incomprehensible loss.”

The statement concludes, “In due course, we will say more when we are ready.

For now, our thoughts and love are with Matty’s family, friends, and everyone around the world who loved him.”

Perry, who opened up about his struggle with addiction in his 2022 memoir Friends, Lovers, and the Big Terrible Thing, was admired by Arquette for his efforts in helping others grapple with addiction. “He assisted numerous individuals,” she affirms. “Getting clean is an arduous battle, and he made a difference by aiding many in achieving sobriety.”

Arquette emphasizes the importance of remembering Perry’s legacy, highlighting his philanthropic endeavors. “He gave back, and that's the lasting impression we should hold on to.

He reached a point where he understood and shared his journey through this beautiful book. Moreover, he used his resources to establish a sober living facility. It is truly remarkable,” she concludes.
