It was a photo-finish at the box office this holiday weekend, with Friday-Sunday estimates indicating that Ice Age: Dawn of the Dinosaurs and Transformers: Revenge of the Fallen each took in $42.5 million. The final result is due to be released this afternoon (Monday). Early indications, however, are that the Ice Age sequel will come out on top by about $1.3 million, according to box office analysts, who say that its final figures will be boosted by strong ticket sales at theaters showing it in 3D, where the premium $2.00 (or so) price for 3D glasses was likely to offset lower ticket prices for children. For the five-day holiday, the 20th Century Fox animated feature did indeed wind up ahead with an anticipated gross of $67.5 versus about $65 million for Transformers. Universal’s Public Enemies also had a solid opening with $26.2 million for the three-day weekend and $41 million for the five-day. Overseas, there was no contest, with Ice Age nailing $148 million over the five days in 101 countries, including 16 where it broke opening records.  In most countries, no other movie even came close.
