The owners of AMC Theatres say a $20 adult ticket price for an IMAX showing of "Shrek Forever After'' at some of its Manhattan theaters was posted online in error.
AMC spokesman Justin Scott said Friday that a limited number of its theaters "posted incorrect pricing.'' He says customers who bought a $20 ticket would be eligible for a refund.
The Wall Street Journal had reported that the $20 price was posted online Wednesday for weekend showings at four Manhattan theaters.
By Friday, three of those theaters had ticket prices from $17 to $19. The AMC Loews Lincoln Square in Manhattan was still selling Shrek IMAX tickets for $20. But Scott said it would be adjusted to $19.
"Shrek Forever After'' is the series' fourth installment, and the first in 3-D.
