Sydney Sweeney has spoken about the impact of the death of her Euphoria co-star Angus Cloud on her and her castmates.

In an interview with Glamour, the 26-year-old said Cloud's death in August came as "such a shock".

When they heard the news, the cast "were constantly on the phone with each other crying", the actress said.

Cloud, who played drug dealer Fezco in the teen drama, was 25 when he died of an accidental drug overdose.

HBO's hit series follows a group of troubled high school students with hard-hitting storylines. It is returning for a third season in 2025, with filming beginning next year.

"I don't think it'll truly feel real or hit me until we're filming and I won't see Angus on set," Sweeney told Glamour.

"[At least] when we are filming, all of our eyes are on each other and we're there for each other, just in a different way than we're able to when we're all in very separate places in the world.

"It's really interesting when someone passes away in our industry, because they're still alive in so many forms."

Shortly after Cloud's death, Sweeney, who is also known for her role in White Lotus, posted a tribute on Instagram.

"You will be missed more than you know, but I'm so blessed to have known you in this lifetime, and I'm sure everyone who has ever met you feels the same," she wrote.

"This heartache is real and I wish we could've had one more hug and 711 run. All my love is with you."

Cloud's father had recently died, and the actor's family said he had "intensely struggled with this loss".

After first airing in June 2019, Euphoria quickly became a hit and was nominated for best drama series at last year's Emmy Awards.

The main character Rue, played by Zendaya, was introduced as a 17-year-old drug addict fresh out of rehab.

Sweeney, who plays Cassie, a teenager with a promiscuous reputation, said the role was an emotional outlet for her.

"Cassie is definitely the closest - especially in season one - to me that I've played and she means a lot to me. But it's almost like therapy: where I can let out so much… that when I go home, I feel free."
