Summer's almost over as 'Phineas and Ferb' wraps production

Summer is coming to an end for the two smart, resourceful animated stepbrothers who are the leads for Disney XD's "Phineas and Ferb" as the show wraps up production after 126 episodes, five one-hour specials, three Emmy Awards (nine nominations) and a record-breaking Disney Channel original movie.

Animation producers Dan Povenmire and Jeff "Swampy" Marsh are moving on from the tales of Phineas Flynn and Ferb Fletcher, two kids constantly trying to conquer boredom during their summer vacation with adventures and inventions. The duo are often outrunning their  tattletale big sister Candace and thwarting the plans of the nefarious Dr. Doofenshmirtz. Their "Last Day of Summer," the title of the season finale, premieres  June 12 on Disney XD, simulcast on the Disney Channel. The series will continue to run daily on Disney XD, and a stand-alone hour-long special -- "The O.W.C.A. Files," which focuses on the organization's best secret agent, Agent P (also known as Perry the Platypus) -- will premiere this fall on Disney XD.

Povenmire and Marsh aren't leaving Disney, though; they're prepping a new show called "Mikey Murphy's Law," which will introduce the fictional great-great-great-great grandson of the Murphy's Law namesake. The show is scheduled for a 2017 premiere.

Before then, every "Phineas and Ferb" episode will be presented in a 73-hour marathon beginning June 9, leading to the finale, including specials highlighting crossovers with Marvel superheroes, a "Lost"-inspired episode and a very detailed "Star Wars" offshoot.

The "Phineas and Ferb" voice cast includes Vincent Martella as Phineas Flynn, Thomas Sangster as Ferb Fletcher, Ashley Tisdale as Candace Flynn, Mitchel Musso as Jeremy, Caroline Rhea as Mom Linda Flynn-Fletcher, Richard O'Brien as Dad Lawrence Fletcher, Dee Bradley Baker as Perry the Platypus, Alyson Stoner as Isabella, Jeff "Swampy" Marsh as Major Monogram and Dan Povenmire as Dr. Doofenshmirtz. Among its more than 150 guest stars have been  Michael Douglas, Michael J. Fox, Jon Stewart, Patrick Dempsey, Ben Stiller, Tina Fey, JK Simmons, Seth MacFarlane, Jay Leno, Kelly Clarkson, George Takei, Simon Pegg, Anna Paquin, Josh Gad and Stan Lee.
