Andy Serkis helped to create two of filmdom’s most celebrated characters, but most people probably wouldn’t recognize him. That’s because the veteran actor’s breakthrough performances — as Gollum in “Lord of the Rings” and the big, misunderstood ape in the 2005 “King Kong” remake — were created using digital technology. Although computer animators relied on Serkis’ performance for the emotional center and movements of both characters, he doesn’t get any face time (aside from a small, secondary role in “Kong”). Serkis is fine with that. [More]
