Alisha Weir and the wider cast of the new film "Abigail" have paid tribute to their co-star Angus Cloud, the Irish American actor who passed away just weeks after filming wrapped.

“Every single cast member was so incredible, and Angus brought so much joy to the set,” Dublin native Weir, 14, told the PA last night, April 17, at the Los Angeles premiere of "Abigail," in which she stars.

“Every single day he would make everybody smile and I’m so so honoured and so grateful, not just to have worked with him, but to have known such a beautiful person who is so amazing and beautiful inside and out.

“He shared that with every single person on the cast.”

Cloud, whose father was from Co Meath, died on July 31 at the age of 25. The Alameda County Coroner later said he died of acute intoxication following an accidental overdose.

Full name is Conor Angus Cloud Hickey, the actor previously said that he was preparing to move to Ireland before he was scouted to feature as Fezco in HBO's hit series "Euphoria."

In "Abigail," Cloud plays a kidnapper, appearing alongside "Scream" star Melissa Barrera, "Downton Abbey's" Dan Stevens, "Big Little Lies" actress Kathryn Newton, and "X-Men" star Kevin Durand. 

Speaking on the red carpet on Wednesday evening, Stevens described Cloud as "unique," adding that he had never met anyone like him. 

"He was like all of our little brothers on set, and we loved him very much, and we miss him very much," Stevens said. 

Stevens added that "Abigail," which was filmed in Ireland, features a tribute to Cloud at the end of the movie. 

"I love that this film has a tribute to him at the end, and he would have loved this; he would’ve laughed his arse off," Stevens told reporters. 

Durand, meanwhile, said everyone spoke of "how good they felt" when they talked to Cloud on set. 

"It was just so nice to meet someone who was just so real," Durand said on Wednesday. 

"He wasn’t concerned with being famous; he wanted to be a good person. We all loved him very much and are all very proud of what he did in this film. I hope he's really happy with is."
