Shrek makers laughing hard

The studio behind “Shrek Forever After” had plenty to laugh about as the film beat a pair of comedies at the North American box office to take the top spot for the third straight weekend. The animated film’s strong staying power and its estimated weekend take of $25.3m (£17..5m) bodes well for DreamWorks Animation, which last month saw its share price dip after the movie suffered a lower-than-expected opening.
