homo indomitus

Does that really mean savage or indomitable man, or are those terms equivalent or interchangeable? They certainly don't seem so to me.

I've seen some minor complaints about the poor Latin translations in the movie, but the dialogue in question was sub-titled and I seem to clearly remember it as "a savage."

The context of the dialogue is very important. Wallace is speaking with the English princess (who is actually French, but married to the son of King Edward) who was sent out to negotiate terms for peace with Wallace's Scottish rebels. Wallace is supposed to be little more than a wild, ignorant barbarian, but when the princess' aide says to her (in Latin) that "he is a lying savage," Wallace utters his classic reply (in Latin, as well) to both of them. From this point forward it is clear to them that this is no ordinary barbarian.
