So, you've discovered that your pet platypus is a secret agent. What now? Well, if you're Phineas and Ferb, the two summer-loving brothers on Disney Channel's hit animated show, Phineas and Ferb, you'd help your duck-billed friend save the Tri-State area!

In the new movie Phineas and Ferb: Across the 2nd Dimension, premiering tonight on Disney Channel, the pair and their pet get sent to another dimension. There, they discover that everyone has a double. Dr. Doofenshmirtz's twin, the evil Dr. Doofenshmirtz2, has successfully taken control of the Tri-State area. Now it's up to Phineas, Ferb, Agent P and their other selves to save Alternate Danville from destruction.

In July, TFK headed to New York City's Times Square to chat with creators Dan Povenmire and Jeff "Swampy" Marsh and with cast members Alyson Stoner and Dee Bradley Baker about Phineas' and Ferb's excellent new adventure. Watch the video above to see what they had to say.
