No dobrze, a co w takim razie z tytułami filmów które zawierają w sobie przedimek "the" jak np. podany przeze mnie "The beast"? Są to błędy w tytułach?
No, they are not. Sometimes the author may want to invite the 'attention' of potential listeners/readers to single out the referent beforehand, to accept something that the reader is not familiar with (yet). It's merely a plea, so to speak, for the reader's acceptance of that referent, that this something exists. Basically, they expect everyone to take it for granted in the sense that this something is already unique.
In a way, it's a sort of cataphoric reference to the unknown because it refers to something that follows the referent.
