Half a year after the release of A Battle of Wits, Choi's second silver-screen appearance was in Attack on the Pin-Up Boys, a 2008 high school Korean film that starred all members of Super Junior except Leeteuk and Kyuhyun. He played the lead role of a controlling and severe class president who was one of the popular possible subjects of being attacked by mysterious forces. Despite positive critical ratings, that film did not do well in the box-office, but all four versions of the film's DVD were all sold out and broke chart records.

Other works

Acting alongside Yoo Jitae, Lee Yeonhee, and Chae Jung-an, Choi was offered a lead role in the upcoming 2008 Korean language film, "Sun Jung Manhwa", who was to play a high school student falling in love with a woman much older than himself. However, Choi turned down the offer to work on his music career in China with Super Junior-M; the role was given to bandmate Kang-in instead.

Choi continued his education after his debut with Super Junior in 2005. He graduated from Hyun Dae High School in February 2006 and later went on to attend Inha University. Always been fascinated with Chinese language and culture, his company arranged him to travel to Beijing, China in 2004 to learn about the country's language and history and stayed there for three months before his return to Korea to prepare for his debut in Super Junior a year later.

Choi is also a drummer, having performed with his senior labelmates, TRAX in September 2006 on SBS's music show Popular Songs due to the fact that their drummer, Rose, had left the band. He is skilled in Taekwondo and became the youngest in Korea holding the fourth rank in the black belt.
