Guests will be able to take part in an energetic and fun-filled meet-and-play experience with Phineas & Ferbat Disney's Hollywood Studios (scheduled to begin in May). Phineas and Ferb -- from the popular television show of the same name -- "know what they're gonna do today": they are going to make a movie all about their crazy adventures. With the help of guests and movie director Cletus Filmore, they will recreate some of their favorite moments...unless they are taking a break to meet with their adoring fans, signing autographs and taking pictures. The fun will take place near the exit to Muppet-Vision 3-D.
