The Phineas and Ferb play-and-greet opened to guests at Disney’s Hollywood Studios on Sunday. Fans had been waiting and wondering when they would appear because the Disney Channel characters had been scheduled to debut May 16. Like with other recently added Disney World character experiences, this one has been designed to be more interactive. In this instance, the pair are making a movie about their crazy adventures and director Cletus Filmore recruits “actors” from the queue to help with the filming. In between takes, guests in line can get photos and autographs from Phineas and Ferb. The Phineas and Ferb play-and-greet is located near the exit to Muppet*Vision 3-D. The experience is operating from 10:30 a.m. to 2 p.m. and 3 to 5:30 p.m. daily, WDWmagic.com reports.
