LOS ANGELES (Variety.com) - Three films are essentially tied at the top of the weekend box office, as of Sunday morning. Warner Bros. and New Line?s ?It? appears to be back on top with $17.3 million from 3,917 locations. But Universal?s ?American Made? and Fox?s ?Kingsman: The Golden Circle? are trailing just behind with $17 million each. Since the numbers are so close, some studios are waiting until later in the day to make the official call.
