No, the movie Arceus that has been distributed in Japan is not the only Arceus that will work for the Heart Gold and Soul Silver Arceus event. That Arceus was special, because of the fact it unlocked a special Pichu event in Heart Gold and Soul Silver. Any Arceus will work for the event in which you can get a Level 1 Dialga, Palkia, or Giratina in Pokemon Heart Gold and Soul Silver.
