Joe Letteri, visual effects supervisor for "King Kong" and "Avatar," said the team was tasked with several challenges in bringing 3-D to the studio tour. Most noticeably, the gorilla-versus-dinos smackdown is entirely seamless, so there are no cuts during the battle, and unlike a typical 3-D movie, the audience isn't always looking in the same direction.
"Everyone is seeing something different because they're not facing the same screen," said Letteri. "Every time someone goes through this ride, they're going to have a different experience depending on where they sit and look. We're making sure that everybody in the tram — whether in the front or the back — experiences something interesting and exciting."
