As two other reviewers duly noted, the fact that for the first 30 minutes said character is dragged around on the leash in her underwear makes the situation even more hilarious.
The movie also does not explain the difference between normal and green Orcs at all, so the audience is going to consider them different races, with the inferior Green race being a cannon fodder, and superior Brown being commanders.
Personally, I don't care much about racism in movies at all, but Warcraft didn't handle the topic in a particularly graceful way.
