 The original idea for the " Road to " episodes came from MacFarlane , as he is a fan of the films of Crosby , Hope and Lamour . The first episode was directed by Dan Povenmire , who would direct the rest of the " Road to " episodes until the episode " Road to Rupert " , at which point he had left the show to create Phineas and Ferb . Series regular Greg Colton then took over Povenmire 's role as director of the " Road to " episodes .
