Trivia

Originally, Bungie wanted to do the first film Halo: Combat Evolved in 3D. But due to the upcoming new 3-dimensional visual effects he wanted to wait to do the next installment in 3D. He later tried to do Halo 2 in 3D, but he decided to do the third in 3D to make it Halo 3D.

The MPAA gave Halo 3 an R-Rating for sequences of strong battle-sequences and sci-fi violence, language and some smoking. However, due to the most brutal scenes removed, it got an PG-13 rating.

There are three different endings of Halo 3: the ending wich shows Master Chief alive. the same, but in this ending Master Chief is killed and does not survive. the ending in which Master Chief survives and starts a family in the epilogue. The last one being removed to leave the door open for a possible fourth installment.

This is Bungie's first film to be re-rated because of an R-Rating. His previous were all given a PG-13 rating on appeal.
