For the first time ever, Wrigley hosted a movie night. The choice was the 1986 movie "Ferris Bueller's Day Off."
In one scene, the title character and his friends attended a Cubs game after a day of skipping school.
The crowd also took part in setting a world record for the most people singing in the round. They performed the song "Danke Schoen," which is part of the movie's sound track.
The screening was held to celebrate the film's 25th anniversary.
