Say a person writes a novel or a script or something along those lines. Now, let’s say that this person creates a character who speaks only in quotes, and then only in quotes taken from a specific character created by another author.
A major part of this new character’s personality would be based on the fact that his speech is entirely comprised of quotes from a previously existing character from another work. The idea is that this new character is attempting to identify himself with the earlier character, and from that the reader may quickly draw insight into his motives and meanings, etc.
Would this be legal? Is this plagiarism, or just shabby post-modernism?
