Opening weekend for Maid in Manhattan and Nemesis was very close.
$18,711,407 (USA) (15 December 2002) (2838 Screens)
$18,513,305 (USA) (15 December 2002) (2711 Screens)
I'm more surprised that a Jlo movie got on more screens than a Star Trek film opening week. That must have been around the time of the whole Bennifer fiasco.
