LOS ANGELES (Reuters) - "Tron: Legacy," a costly 3D sci-fi movie that Walt Disney Co has promoted for more than three years, took the top spot at the North American box office, but with a disappointing weekend haul of $43.6 million, according to estimates issued by the company on Sunday.
Industry observers had been expecting a three-day start in the $50 million range. As openings go this year, the massively hyped sequel to an obscure 1982 movie failed to crack the top-10, and observers have said it will need to rely on strong overseas business to break even.
