To celebrate the release of Phineas and Ferb The Movie: Candace Against the Universe, which debuts on Disney+ this week, we sat down with the show’s co-creators to chat about the hilarious new adventure.

The show has been wildly successful since its inception back in 2007 with over 222 episodes made so far, so it was inevitable a film version would come to light sooner or later (they have made films before, but this is the first official “cinema” episode). Povenmire and Marsh – both wonderfully warm and funny gentlemen – tell us about the challenges of making a feature-length version of the show and keeping up with audience expectations.

They also tell us how, through all the influences on the show, it was BBC’s Blackadder – created by Rowan Atkinson and Richard Curtis – that was instrumental in making it all come together: “We watched the whole series and then put it straight back on from the beginning again!”

Phineas and Ferb The Movie: Candace Against the Universe is an adventure story that tracks stepbrothers Phineas and Ferb as they set out across the galaxy to rescue their older sister Candace, who after being abducted by aliens, finds utopia in a far-off planet, free of pesky little brothers.
