film of all time. Murder mystery Paradise Murdered was a surprise hit in 2007, with Kyu Hyun Kim of Koreanfilm.org calling Park "an inspired choice for the ostensible protagonist, projecting fatigued compassion and cold calculation in equal measure, his obsidian pupils glistening with streaks of chilling obsession." In 2008, he starred in the period drama Modern Boy, a dramatic love story set in 1930s Gyeongseong or old Seoul, when Korea was under Japanese colonization (1910–45). Park played the role of a rich, hedonistic playboy who cannot care less that his country was colonized, then falls head over heels in love with a beautiful and mysterious independence fighter (Kim Hye-soo). After small supporting roles in Shim's Family (also known as Skeletons in the Closet), and Good Morning, President, Park joined the ensemble cast of A Million as one of eight participants who take part in a TV reality show in Perth, Australia but discover that they must literally survive to win the prize of 1 million dollars. In 2010, Park headlined Kang Woo-suk's blockbuster mystery thriller Moss, playing a young man who comes to a rural village after hearing about his father's death and later becomes embroiled in its hidden secrets. Park's casting was received enthusiastically by fans of the source material, Yoon Tae-ho's hugely popular online graphic novel series. Heartbeat explores a familial love battle of wills, as Yeon-hee (played by Yunjin Kim of Lost fame) whose daughter is in desperate need of a heart transplant, tries to convince a brain-dead patient's son (Park) to sign off on the transplant, but he refuses and instead investigates his mother's fall. He then appeared in the low-budget indie End of Animal, because he found the script "very interesting." Park next starred in War of the Arrows, a fictional tale set in the Joseon Dynasty, which follows Nam-yi (Park) on his search for younger sister Ja-in after she is kidnapped by Qing Dynasty soldiers during an invasion. As he slays enemy soldiers with his bow and arrow, he is confronted by Jushinta, a Manchu enemy commander also well known for his archery prowess. Arrow made headlines by selling to distributors from six countries at the Cannes film market and becoming the highest-grossing Korean film of 2011. Park won Best Actor honors at the prestigious Grand Bell Awards and Blue Dragon Film Awards. He returned to the big screen in A Muse, a film
