The Unrated Edition reinserts 2 major scenes amounting of 10 minutes. The first one is an exchange between Drake and Danica where both shared their past including Drake being 'there' during the crucification. He then seduces her. The other one is right after the final fight between Drake and Blade. The doctors were about to perform an autopsy on Blade when he just simply gets up as if 'resurrected' and leaves the morgue. However, the fate of the doctors were not revealed.
The unrated extended edition also has a very different and much more ambiguous ending than the theatrical release.
Blade Trinity DVD has 2 versions of the film. Theatrical cut, and an unrated extended edition.
In the Unrated Extended edition, there's a deleted scene with Danica and Drake. Danica's wearing a cross, and tells her he was there when they crucified him.
Two versions are available in Germany: the uncut version with a "Not under 18" rating and an edited version (with a "Not under 16" rating) which misses ca. 3 minutes.
