毕业于东国大学表演学院的新面孔洪京仁在 1990 年代初的韩国经典电影《我们扭曲的英雄》（1992 年）中首次亮相银幕，年仅 16 岁。在十几岁的时候，他继续出现在 1990 年代中期一些最重要的电影中，例如《永恒的帝国》（1995 年）和《单一的火花》（1995 年）。大约在这个时候，他也开始出现在电视剧中。20年来，他一直稳定地在银幕上担任电影的联合主演，例如2001年的热门黑帮喜剧《嗨！佛法。在离开电影院几年后，香港于2013年重返大银幕，出演了热门间谍剧《秘密地》，然后在2014年与金仁权一起出演了以朝鲜为背景的电视剧《使徒》。

The fresh-faced HONG Kyung-in, who graduated from the Dongguk University’s School of Acting, debuted on screen at the tender age of 16 in the early 1990s Korean classic Our Twisted Hero (1992). While still a teenager he went on to appear in some of the most important films of the mid-1990s, such as The Eternal Empire (1995) and A Single Spark (1995). It was around this time that he began to appear in TV dramas as well. He has remained consistent on screen, taking co-starring roles in films for 20 years, such as 2001’s hit gangster comedy Hi! Dharma. After a few years absent from cinemas, HONG returned to the big screen in 2013 with a part in the hit spy drama Secretly Greatly and then starred alongside KIM In-gwon in the issue-raising North Korea-set drama Apostle in 2014.
