Marsh moved back to the United States where Disney accepted the pilot episode and ordered a full 26 episode season. The pair still needed to convince overseas Disney executives to pick up the series, so instead of a conventional script, they recorded the storyboards for "Rollercoaster”. Povenmire then spent time dubbing over it with his voice for each character, along with sound effects and narration. When the recording was sent to the executives, they accepted and the series was officially green lit for the company's cable network Disney Channel. It officially began broadcast on February 1, 2008 and the cartoon name was called Phineas and Ferb.
