Watch out, upcoming 'Dirty Dancing' remake and 'Rock of Ages'; if this week's box office is any indication, the '80s nostalgia wave is over. Last week's winner, 'Real Steel,' beat all three newcomers, including reboots of two Reagan Era titles. According to Sunday's studio estimates, the robot-boxing saga edged out the re-do of 'Footloose' and beat the tar out of horror prequel 'The Thing.' Meanwhile, not even a trio of comic heavyweights could make a birdwatching comedy fly, so 'The Big Year' debuted in ninth place with a paltry $3.3 million.
