"Punkrocker" is a song written and originally performed by the Swedish electronic/alternative group Teddybears. The song first appeared on their 2000 album Rock’n’Roll Highschool, and was covered later that year by Caesar's Palace (later known as Caesars), a band which also includes Teddybears member Joakim Åhlund. The song has been covered multiple times, with the best known version internationally being a 2006 re-recording by Teddybears with American singer Iggy Pop on lead vocals. This version was a minor hit in the United States,[when?] and appeared in a Cadillac ad campaign in 2007. It was also featured in the 2025 film Superman. The Teddybears' single, "Punkrocker" (featuring Iggy Pop), is featured in a Cadillac television commercial directed by Daniel Askill, titled 'Roll' and features a time-line of Cadillac automobiles, from the original 1902 Cadillac to the 2007 Cadillac XLR sports convertible. The song also appeared in the background of a scene of NBC's Bionic Woman. Thomas Rusiak's version "Hiphopper" can be heard in Kevin Smith's 2001 film Jay and Silent Bob Strike Back. The song is featured in the end credits of the 2025 DC Universe film Superman.[3] The song serves as a callback to an earlier scene in the film, in which Lois Lane (portrayed by Rachel Brosnahan) describes herself as "punk rock" due to her cynicism, while describing her boyfriend Clark Kent (portrayed by David Corenswet), as more kind and trusting, to which Kent replies "maybe [kindness and trust are] the real punk rock." The song saw a huge increase in streaming numbers following its inclusion in the film, going from 1,572 streams as of July 4 to nearly 190,500 by July 12, the day after Superman released. Iggy Pop expressed his approval of the song's inclusion to The Hollywood Reporter, saying "I always thought the track had soul. Superman is the best friend you could have.”
