Disney will celebrate Opposite Day. The studio is developing a high-concept comedy with that title and has hired Nancy Drew scribe Tiffany Paulsen to write it.

Opposite, based on an idea by studio production president Oren Aviv, centers on a corporate hatchet man who wakes up one morning and finds he must follow the exact opposite of his normal routine.

Paulsen wrote 2007's Drew, an adaptation of the classic children's detective series for Warners. She also is attached to write Further Adventures in Babysitting, Disney's reboot of the 1980s teen hit.

Aviv has conceived of a number of movie ideas that became hit Disney projects, including the adventure franchise National Treasure, for which he received a story credit.
