On August 12, 2011 Billy Crystal went to a 20th anniversary screening of "City Slickers". When he was asked about his return to the role of Mike Wazowski he said, "That's why I'm a little hoarse. I spent five-and-a-half hours today for our fourth session on "Monsters Inc. 2"." Crystal has said that he and co-star John Goodman are having a blast together and describes the script as "really great" and "hilarious". Crystal also gave little details of the story of the movie. He described, "It's college pranks with monsters. And I wear a retainer. Mike has a retainer."
