Production
The film is the first production of CJ ENM's O'pen project, which is dedicated to discovering and developing new creative talent. Ko Jun-seok's original screenplay made it to the top six of the competition and caught the attention of director Paek Seung-hwan, who decided to use the story to explore his doubts about faith and religion. The original title was At the Border '': Only God Knows Everything, but Paek was so intrigued by the subtitle that he decided to retitle the film.Filming began on March 3, 2023, and five days later, it was announced that the main cast would consist of Shin Seung-ho, Han Ji-eun, Park Myung-hoon, and Jeon So-min, while Yoo Sung-joo, Lee Jung-ok, and Nam Joong-kyu would play supporting roles. The crew wrapped filming in November 2023.
Shin Seung-ho had previously been directed by Paek in Double Patty, forming a close friendship with him; the director didn't say much when he offered him the lead role in Only God Knows Everything, other than that he thought Shin would look good in a cassock. Shin accepted because the character had little in common with him or his previous work, thus presenting a challenge. Being a Protestant, the actor interacted with several Catholic priests to better understand the role.
Park Myung-hoon gained 10 kg to play the role of the shaman. Jeon So-min was cast because Paek was impressed by her intense gaze in the 2021–2022 TV series Show Window: The Queen's House'', even though the role was originally intended for an older actress.
The soundtrack was entirely composed, arranged and performed by Lee Sang-hoon for 4Bros. Music and was released on streaming platforms on August 22, 2025, the same date as the film.
