User blog comment:Mobo85/Walt Disney Studios Cancels "Phineas and Ferb" Feature Film/@comment-4037231-20130906122225

From what i can gather, it turns out the film wasn't canceled. It was just stalled cuz they are busy with the star wars special. After all, they were talking in interviews about how the script was being worked on, and how they had extra time for songs, and they mentioned the entire premise of going to the real world and it being all roger rabbit-y and stuff.

So we just need to wait a few extra years, it's happening. just...not now.
