“Along with the Gods” series is considered one of the most successful webtoon-original movies. This is because not only did it make a hit with a great box office success but also had a positive impact on various sectors such as adaptations, CGs, and production methods. Based on a series of webtoons published by writer Joo Ho Min, the movie depicts the three guides, Kangrim (Ha Jung Woo), Duckchoon (Kim Hyang Gi) and Haewonmaek (Ju Ji Hoon), leading the dead to the trials held in hell with the purpose of reincarnation. The original webtoons of “The Underworld” and “This World” were each turned into “The Last 49 Days” and “The Two Worlds” and have taken in an unconventional way of filming by filming two films simultaneously. While this method reduced the filming period and production cost, it was also a risky production method.

Before the release, there were more worrisome responses than expectations. This soon became a reality. Originally, Along With the Gods: The Two Worlds was supposed to be released in the summer of 2017, but ended up being delayed to December due to last-minute production problems. Also, when the trailer was released, most fans were enraged as the popular character, Jin Gi Han, from the original work, was missing. However, despite all the issues, the movie continued to be a box office hit after its release. It attracted 2.72 million viewers during the first weekend after its release and surpassed 10 million viewers in 16 days. Also, the movie attracted 14.41 million viewers, earning the entire budget (33.00 million USD) of the two movies with just Along With the Gods: The Two Worlds. This is the first webtoon-original movie to attract more than 10 million viewers and surpassed Inside Men to top the box office of webtoon-original films.

The second series, Along with the Gods: The Last 49 Days, was also a huge success. Following the first film with 12.27 million viewers, the second film also surpassed the 10 million mark, becoming the first Korean film to hit double 10-million-viewers movies with both series. Ma Dong Seok, who made a surprise appearance in the first film, joined the second film in earnest. Also, the exciting story that links the three guides’ past fates was unfolded, grabbing the attention. With the success of the first two series, expectations are high for the upcoming sequel; the production team confirmed their plans to film the next two series simultaneously once again, hoping to release them in the following year.
