Choi Siwon was raised in a strict, Protestant family from Seoul, South Korea. After Choi's talents were scouted in the Starlight Casting System in 2003, his parents initially disapproved him to pursue in an entertainment career. After consideration, his parents approved Choi to sign under the talent agency SM Entertainment, where he was trained in areas of singing, acting, and dancing. He made his first appearance in a music video of The Grace's Dana when she was still a solo singer in 2003. A year after, Choi made a brief appearance in the short drama, Precious Family. In early 2005 Choi's talent agency released an announcement that Choi would officially debut as a member of the large all-boy music group, Super Junior, which was slated to make an official debut near the end of the year. A few months before debut, Choi made his first media appearance with Han Geng as a runway model, in a fashion show by Bum Suk.
On November 6, 2005, Choi officially debuted on SBS's Popular Songs with the reason of Super Junior, performing the group's first single "TWINS (Knock Out)."
In early 2008, SM Entertainment placed Choi Siwon in a seven-piece Chinese subgroup of Super Junior, Super Junior-M. The subgroup specializes in singing Chinese versions of Super Junior's Korean songs, bringing the K-pop influence over to the Chinese music industry. Super Junior-M is the first international music group in the Chinese music industry to have members of both Chinese and Korean descent. Super Junior-M debuted in China on April 8, 2008 at the 8th Annual Music Chart Awards with the release of their first single music video, "U".
Choi is one of the few members of Super Junior who actively appears on variety shows. Choi makes frequent appearances on Love Letter and other popular South Korean variety programs. Choi is also a popular symbol for endorsements, being an endorser of many items in South Korea. In early March 2007 he has been picked up as the presenter of Thailand's 12 Plus Powder and went to Thailand several times a year to shoot the commercial.
Although initially trained to be a singer, Choi has made many appearances in dramas. He made his first official drama appearance on KBS's 18 vs. 29 in 2005, playing the role of young Kang Bo-nam. He later joined the cast for the Korean drama mini-series Spring Waltz in 2006. Choi's first lead role was in the mini-drama, Legend of Hyang Dan , released on September 2007.
Choi was chosen to be part of the epic film A Battle of Wits acting alongside Hong Kong actor and singer Andy Lau. A Battle of Wits is a big budget film with joint collaboration from South Korea, China, and Japan, and was released in China and Hong Kong on November 23, 2006. The film was released in Korea in early 2007. Choi has promoted the movie in China with a short tour of four cities at the end of November. Choi also received praises from co-star Lau, stating that Choi is a wonderful actor and is a good example that can be set for young Hong Kong idols.
Acting alongside Yoo Ji-tae, Lee Yeon Hee, and Chae Jung An, Choi was offered a lead role in the upcoming Korean language film, "Sun Jung Man Hwa", who was to play a high school student falling in love with a woman much older than himself. However, due to Choi's busy schedule with the new Super Junior subgroup, Super Junior-M, the role was given to Kang-In instead.
Choi continued his education after his debut with Super Junior. Choi graduated from Hyun Dae High School in February 2006 and later went on to attend Inha University. A year before his debut with Super Junior he traveled to Beijing, China to learn about the country's language and history and stayed there for six months. 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. Choi is nicknamed Simba by his bandmate Kim Heechul. Members joke that he has the same smile as the Joker from Batman. His members also call him Horse because of his looks and his height.
