TRON OFF TO SLOW START

Tron Legacy, a costly 3D sci-fi movie that Walt Disney has promoted for more than three years, opened disappointingly at the weekend box office in America. Tron, a massively hyped sequel to a 1982 movie, earned $43.6m (£28.04bn) during its first three days of release, Disney said yesterday. Industry observers had been expecting a three-day start in the $50m range. The movie is said to have cost $170m to make.
