“The movie has nothing to do with Harry Potter,” protested the 11 year old star of the film, Zain Khan.
In the film, a 10 year old boy nicknamed Hari Puttar moves to Britain and recovers a stolen top secret computer chip originally developed by his father for the Indian Army.
A key difference is that unlike Harry Potter, Hari has no magic powers and is certainly no wizard.
Not that Warner Bros care. To them, the title itself is too close.
Titles are not protected by copyright law. We’re not sure whether they’re suing under trade marks law (Warner Bros have several Harry Potter trade marks in Australia, presumably they have registered the title in India too), or passing off. Either way, the Harry Potter series has a formidable reputation so it should be an interesting case.
