I was excited because the script had a Centipede sequence and a Pac-Man sequence, but what the first draft of the script did not have was Donkey Kong. After months and months of meeting with the board of Nintendo they agreed that we were going to treat Donkey Kong with respect and the proper gameplay, which was very important, and bringing Donkey Kong into the film was a slam-dunk for us.
