Now that “Shrek” the ogre is playing out his final chapter on the big screen, DreamWorks Animation SKG Inc. is turning to trolls to bring in the green. The Glendale, California-based movie studio said Wednesday it has agreed with Dam Things of Denmark to bring the popular doll franchise, Good Luck Trolls, to movie theaters. The ugly but cute toys with wild hairdos became popular in the 1960s and had a revival in the 1990s. They were created by Danish woodcutter Thomas Dam, who carved the doll in 1959 when he couldn't afford a Christmas gift for his young daughter Lajla. A release date was not announced.
