'Real Steel' may be your typical underdog tale (aside from the giant robots), but it didn't behave like an underdog at the box office. Hugh Jackman's brawling-'bots saga came out swinging and easily knocked all rivals out of contention, surprising no one with its estimated $27.3 million victory. George Clooney's Oscar-baiting drama 'The Ides of March' also did about as well as expected, debuting in second place with an estimated $10.4 million.
