Gladiator Easter Egg - Zulu Zulu Zulu!

Watch the movie Gladiator, starring Russell Crowe. The movie begins with a battle between Romans and some Germanic tribe. If you listen to the chant from the Germanic Tribe, you can hear "ZULUUUUUUU" several times quite clearly. This chant is taken directly from the old movie "ZULU" (Starring Michael Caine), where, when British Troops are under siege from Zulu Warriors, the Zulu war cry, perhaps obviously, is ZuLU. In fact, I don't even know if this is really an Easter Egg, but it was damn interesting when I clued in. If anyone can post a connection between the two movies, I would love to read it!
