did mark wahlberg do his own singing in the movie rockstar
Rock Star (2001 film) Wahlberg spent five months preparing for his role as Chris Cole, working with a vocal coach, growing his hair, attending the metal scene and wandering around Los Angeles in-character.[9] A concert scene was shot at the Los Angeles Memorial Sports Arena before 10,000 Metallica and Megadeth fans.[10] While filming one Steel Dragon performance, the crew pranked Wahlberg by playing Marky Mark's "Good Vibrations" instead of a rock track, and footage of this is featured during the film's end credits.[11] By 2001, Warner renamed the project from Metal God to Rock Star in order to attract a broader rock fandom instead of just metal fans.[12]
