While the new Epcot attraction, Disney Phineas & Ferb: Agent P’s World Showcase Adventure, won’t open until later this summer, three big talents behind the hit Disney Channel and Disney XD animated series got a sneak peek on Wednesday – along with Agent P himself! Dan Povenmire and Jeff “Swampy” March are co-creators of “Phineas and Ferb” and actor Vincent Martella gives voice to Phineas Flynn. The trio toured World Showcase as Walt Disney Imagineering revealed some of the new attraction’s secrets – and then swore them to secrecy. The game is based on the wily secret-agent alter-ego of Phineas and Ferb’s pet, Perry the Platypus. Transforming into secret agents, Epcot guests will use a “high-tech secret agent device” to scour World Showcase for clues, evil “Inators” and – with a little bit of luck – help Agent P defeat his nemesis, Dr. Doofenschmirtz. The statue of Dr. Doofenschmirtz you see at the end of the video was part of a Walt Disney Imagineering test, and was taken out before guests arrived for the day.

In addition to creating “Phineas and Ferb,” you can also hear Dan Povenmire and Jeff “Swampy” March on episodes of the show. Dan writes and performs songs, as well as providing the voice of Dr. Doofenschmirtz. Swampy also writes songs and voices Major Monogram.
