SJ's new development

The Super Junior members were one of the first Korean idols to begin television presenting and radio hosting. Heechul was the first in the group to be a selected MC for the music programs Popular Songs and Show Music Bank. He was also the first in the group to host radio shows, and co-hosted Youngstreet Radio Show with ex-M.I.L.K. member Park Heebon in early 2005. Heechul has also been the MC for the Dream Concert since 2008. Leeteuk, Kangin, and Shindong made their MC debut on Mnet's music program M! Countdown five days after Super Junior's debut performance. In August 2006, both Leeteuk and Eunhyuk founded their own radio show, Super Junior Kiss the Radio, which has become one of the more tuned-in radio channels in the country.

The group also founded their own reality television program, and on November 11, 2007, the premiere of Explorers of the Human Body aired on SBS. The humorous show introduced the thirteen members as regular guests for the program, answering curious questions and doing demonstrations involving the human body. The show has been the highest rating program of the reality line-up every Sunday, but due to Super Junior's tight schedule, the program ended quickly with thirteen episodes on February 3, 2008. The popularity of the program had inspired producers to create a second season, although no announcements of producing the next season has been announced.

Twelve members, excluding Kyuhyun, appeared in the group's debut film Attack on the Pin-Up Boys. The first film released by SM Pictures, it premiered on July 26, 2007 in Korea. "Wonder Boy", performed by Super Junior, is used as the theme song of the film. Although the film was promoted as a typical high school comedy, the movie gained positive reviews from critics, praising that the movie had a well-oriented plot unlike most idol films. However, ticket sales remained low in the premiere month despite its unexpected success in the sales the first week. The film was a box-office bomb, failing to attract more than 102,600 admissions and was proven to be a big loss for SM Pictures. However, both versions of the film's DVD became a best-selling record and were sold-out in both Korea and oversea markets, which was more than enough to make up for the production loss of 8.5 billion won.

Siwon was among the first of Super Junior to have participated in silver-screen productions, appearing in the Hong Kong historical action drama film, A Battle of Wits as the large supporting role of Prince Liang Shi in 2006. The cast promoted the movie throughout China with a short tour of four cities in November 2006. While the film received mixed reviews, Siwon garnered positive notices for his performance. He also received praises from co-star Andy Lau, stating that Siwon is a wonderful actor and that he "sets a good example for young Hong Kong idols."

In 2007, Heechul, Kangin, and Shindong lent their voices to the three chipmunks in the Korean release of Alvin and the Chipmunks.

In 2008, Kangin had a major role in the Korean-language film, Hello Schoolgirl.
