Apparently Warner Bros is up in arm about an Indian film with a character called Hari Putter and have taken court action against the producers of the film.
Hari Putter however has no magical powers and there is no magic alternate world in the movie.
Meanwhile there is a 1986 film called Troll which has a boy character called Harry Potter whom actually discovers he has magical powers and enters an alternate magical world to fight monsters.
Perhaps Warner Bros would like to sue the producers of that film for coming up with the character over a decade before that anoying female british writer plagiarized it.
