A few weeks Disney announced that they would be combining the worlds of Phineas and Ferb and Star Wars. There were no details revealed at the time about the kind of story they would tell, but in a recent interview with EW, Phineas and Ferb creators Dan Povenmire and Jeff “Swampy” Marsh offered some details on the crossover.
“All of [the plot of A New Hope] happens exactly the way it did, but we find out that Phineas and Ferb are Luke’s neighbors on Tatooine and become embroiled in the adventure. Our story all takes place as if you had a slightly wider shot, you could see our characters. Or if you just waited around five minutes after this [Star Wars] storyline, our characters would pass through, which was really really fun to do.”
That sounds like it could be fun. They went on to talk about the the voices of the Star Wars characters saying,
“The Star Wars actors are now all 40 years older, so they don’t sound quite the same, so we’re trying to find people who sound like they did when they were young. The guy we had come in to do Harrison Ford sounded so much like young Harrison Ford. It was like, if you didn’t look up you thought, ‘We have Harrison Ford in the booth!’”
They go on to tease that there will be some cameos though from “a few fun folks that also really fit in in a weird way with the whole Star Wars universe.”
