Universal Studios and Warner Bros. are partnering again to bring The Wizarding World of Harry Potter attraction to Universal Hollywood, reports Variety. The question that remains is where the $200 million attraction will be located. Universal Studios Hollywood is much smaller than Islands of Adventure and Universal Studios Orlando where the original is located. The studios are hoping to open the second Potter world in 2015. Wizarding World in Orlando increased attendance to Islands of Adventure by 20% in its first six months and 41% in its first year.
