Ferris Bueller 2: Another Day Off is a sequel to the 1986 film Ferris Bueller's Day Off. It was going to be directed by John Hughes, with the original cast reprising their roles, but as much older people. 
Ferris, now around 40 years old, is suffering a mid-life crisis. To try to relive his youth, he gets help from Cameron, now his manager, and they take a day off from work.
Why It Was Cancelled
- Director John Hughes said that the first movie was "about a singular time in your life" and that this movie would be a lame rehash of events.
- John Hughes wasn't a big fan of sequels (despite writing the scripts for both Home Alone 2 and Home Alone 3).
- Matthew Broderick, who played the main character wasn't interested in returning for a sequel.
- John Hughes died in 2009.
- It is highly unlikely that there will ever be a sequel now, especially since Matthew Broderick is too old to play the title character and John Hughes is dead.
- Ferris Bueller's Day Off is a standalone film.
- The script is completed, however the script is currently staying in Paramount's development vault and will likely remain there.
