We've mentioned the strength the box office has shown in recent months a few times. Box Office Guru details the continued strength:
Following a very pricey marketing campaign, DreamWorks Animation's 3D animated film Monsters vs. Aliens delivered on its promises and attracted the largest opening weekend of any film this year leading the overall marketplace to its best performance in over a month. Big muscles were also flexed by Lionsgate which enjoyed one of its biggest horror openings ever with The Haunting in Connecticut which landed in second place with a powerful launch of its own. The top ten films sold $135M worth of ticket stubs making it the best non-holiday tally of 2009.
