wonder boy

Attack on the Pin-Up Boys
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.[78] 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 it's unexpected success in the sales the first week.[79]
Throughout the remaining of the year, the film failed to attract more than 102,600 viewers and was proven to be a big loss for SM Pictures.[80] However, both versions of the film's DVD became a best-selling record and were sold-out in both Korea and oversea markets, which is more than enough to make up for the production loss of 8,500,000,000 won.
