How is ”Black Nuns” starring Song Hye Kyo different from ”Priest” starring Kang Dong Won?

Director Jang Jaehyun has endorsed the film "Black Nuns." The film "Black Nuns" is about a group of people who embark on a forbidden ritual to save a boy possessed by a powerful evil spirit.
It is a sequel to "Priest: The Devil's Burial" (hereafter "Priest"), which opened a new path for Korean occult films and attracted 5.44 million viewers, and is sure to raise expectations.
Since "Priest" was a huge hit, there must have been a lot of pressure to continue that worldview, but director Kwon Hyuk showed courage.
Director Kwon said, "I was a fan of 'Priest' and liked director Jang Jaehyun's work. Since it's a sequel, I feel a lot of pressure.
"It was a difficult role, but I was able to work with great actors and the best staff, so I took on the challenge with courage," she said.
"It is prohibited to participate in the film. But in this film, the very act of participating was refreshing. I think that's another interesting point," he said, "I'm looking forward to comparing it with 'Priest.'"
"There must be some connection," he added. Above all, Director Kwon said he had spoken to Director Jang Jaehyun separately on the phone. Director Kwon said, "Director Jang Jaehyun and I both had a mutual interest in Mija.
"I've known him for a long time since I made Ng Saeng's short film. He's a director I personally really like," he said, "I spoke to him on the phone once before filming and once during filming. I'm very happy to be taking over the baton of this wonderful work."
"I wanted to do it because no one else had done it, and director Jang Jaehyun also supported me. I want to make it look natural for all the fans who love director Jang," she said.
"Black Nuns," which is also supported by director Jang Jaehyun, is expected to captivate audiences with its unique charm while inheriting the worldview of "Priest."
