LOS ANGELES -- The robot boxers of "Real Steel" and the dancers of "Footloose" are in a tight fight for the box-office title. The Hugh Jackman tale about machines in the boxing ring took in $16.3 million, which would make it the No. 1 movie for the second-straight weekend, according to studio estimates Sunday. But "Real Steel" came in barely ahead of the remake "Footloose," which opened with $16.1 million. The movies are close enough that they could switch rankings once final numbers are released Monday. Studio estimates are based on actual business Friday and Saturday and projections for Sunday based on how well similar movies typically hold up. An executive at Disney, which is distributing "Real Steel" for DreamWorks Pictures, said he expects his movie will come out on top because of strong family crowds during day-time shows Sunday. "Absolutely," said Dave Hollis, Disney's head of distribution.
