'Treasure Island' actor Park Hyung-sik surprised fans by revealing a blooper video.

Park Hyung-sik posted behind-the-scenes footage from the filming of the SBS Friday-Saturday drama 'Treasure Island' on his Instagram account on the afternoon of 23rd. In the video, he sarcastically delivered lines to his co-star Kwon Soo-hyun, saying, 'I heard a guy like you became a gangster, so I worried about the country.'

However, Kwon Soo-hyun replied, 'I didn't become a gangster,' and the surrounding staff burst into laughter. The original line was 'not a gangster' but 'inspector.' Accordingly, Park Hyung-sik casually made a mistake while saying, 'Ah, sorry,' and wore an awkward smile. Thanks to this, the atmosphere on set became even more cheerful.

Park Hyung-sik revealed this episode, adding a message saying, 'Ah, it was an inspector..?' and joked around.

Meanwhile, the drama 'Treasure Island,' in which Park Hyung-sik is active, tells the story of Seo Dong-joo (played by Park Hyung-sik), who hacks into a political slush fund of 2 trillion won and fights with everything on the line to destroy the absolute evil that killed him and bring down that world. Park Hyung-sik plays Seo Dong-joo, a man filled with deadly ambition aiming to rise to greater heights.
