Disney and DreamWorks's Real Steel , starring Hugh Jackman, is expected to light a fire under a sluggish box office this weekend, with most forecasters suggesting that the movie will earn around $25-30 million. That would amount to more than twice the expected ticket sales for Sony's The Ides of March , starring George Clooney and Ryan Gosling, the only other film opening wide this weekend. But Real Steel cost a reported $110-120 million to produce. March cost one-tenth of that. The two films will be up against a slew of holdovers that are each expected to gross much less than $10 million. Not among the holdovers is Disney's The Lion King, which ended its limited run last weekend with $71.9 million, making it the highest-grossing movie ever for September.
