Warner Bros. found that investing in the Harry Potter Warner Bros. Studios in London, England, was a wise decision. Although the construction cost was undoubtedly in the nine figures, it was a wise investment because Warner Bros. profits handsomely from HP Studios. Warner Bros. collected almost $50 million in revenue from this tourist attraction in 2020, despite everything being closed.
