Untitled Phineas and Ferb Movie

What if Phineas and Ferb never met?

Dr. Doofenshmirtz’s latest time‑travel experiment backfires, erasing the moment Phineas’ mom meets Ferb’s dad — meaning the boys never become brothers and every day is merely adequate. As reality unravels and the future hangs in the balance, Phineas and Ferb must restore the timeline before it’s too late.
