The first Disney-Marvel crossover animated TV special, “Phineas and Ferb: Mission Marvel,” has begun production.

Scheduled to premiere next summer, the telepic will mix Marvel heroes including Spider-Man, Iron Man, Thor and Hulk and villains including Red Skull, Whiplash, Venom and M.O.D.O.K. into the world of Disney Channel animated series “Phineas and Ferb,” with the latter’s creators and exec producers Dan Povenmire and Jeff “Swampy” Marsh at the helm.

“Our partnership with Marvel has yielded big returns this year — first with the launch of the Marvel Universe block on Disney XD, and now with production beginning on (this) special,” Disney Channels Worldwide prexy and chief creative officer Gary Marsh said.

“Phineas” has been the most-watched animated series in primetime among kids 6-11 for five consecutive years.

” ‘Phineas and Ferb: Mission Marvel’ is an exciting animated special for everyone at Disney and Marvel,” said Dan Buckley, publisher and prexy of Marvel Worldwide print, animation and digital. “It’s a thrilling opportunity for these two franchises to take advantage of each other in a way that may go beyond this one special.”
