What Could Have Been: Early promos made it seem like the show would revolve around a love triangle between Nico/Chad/Sonny, especially the Japanese promos. Some Season 1 episodes still somewhat played with this concept, for example towards the end of Sonny With A Chance of Dating when Chad showed he wasn't willing to oppose Nico as he was standing up for Sonny.
Bridgit Mendler was in the running to play the role of Sonny (then named Molly).
Sonny With A Chance is the only multi-camera series on Disney Channel not to be produced by "It's A Laugh Productions" since that company started producing shows for Disney Channel. It was also the first Disney Channel series to premiere and be filmed entirely in high-definition.
