20 Things You Didn’t Know About Iron Man 2
4. John Debney Recorded The Movie's Score In Just FOUR Days
John Debney's musical score for the movie was roundly praised by fans and critics, even if some felt that it had to unfairly compete with a barrage of AC/DC songs.
However, Debney's achievement is especially impressive when you consider that the composer had a mere four days to record the movie's score, per scheduling limitations.
It's not uncommon for film scores to be completed late in production, but even so, composers often spend 4-6 weeks writing and recording the score, yet for the latter part of the process, Debney got it done in just four days.
