Principal photography began on February 1, 2021 and concluded on May 1, 2021. Kamnik, Slovenia, (14 miles north of Ljubljana, Slovenia's capital) is the primary filming location of 'Infinite Storm.' Most of the movie was shot on location in and around the town. Filming took place on Velika Planina, a nature trail above Kamnik. The cast and crew also filmed some footage in Kamniska Bistrica Valley, which lies close to the source of the Kamnik Bistrica river. Some scenes were shot at International Picnic Center (aka Pri Jurju) in the same region.
