The boy wizard franchise, based on the books by J.K. Rowling, has topped a new Samsung Electronics list.

Prison drama The Shawshank Redemption, which is based on a Stephen King novella titled Rita Hayworth and Shawshank Redemption, comes in second, while director Peter Jackson's adaptations of The Lord of the Rings trilogy is third.

The poll also features the worst big screen adaptations - the Twilight films and the Da Vinci Code have been named the least popular book-to-movie ventures.
