Superman gave a big lift to Time Warner in the second quarter. Theatrical ticket sales for the company's Warner Bros. film division produced stronger-than-anticipated earnings during the quarter, thanks mainly to the success of Man of Steel and the Great Gatsby. Net income for the quarter soared 86.7 percent to $771 versus $4413 million during the same quarter a year ago. The results propelled a surge in Time Warner's share value, which, at midday trading on the Nasdaq, rose to $66.00, a 52-week high.
