Actor Allusion: When Cat Deeley guest stars as the Vice Principal in "Wild It Up", CeCe talks about being a dancer on Shake It Up Chicago, to which the Vice Principal responds with "so you think you can dance?"
CeCe has dyslexia just like her actress.
Zendaya Coleman is a vegetarian and so is her character. Also, she's been dancing since she was a kid, the same age as Rocky.
Averted when she's offered a modeling job. Bella Thorne is a model.
Logan is an example twice!Leo Howard played the title character in an independent movie called Logan before he was cast in Shake It Up. Additionally, Logan was almost going to be Georgia's stepson. When you think about who portrayed young Georgia in "My Bitter Sweet 16 It Up," this becomes very awkward.
Additionally, Ty and Logan's "frenemy" relationship may remind viewers of Jack and Smooth from the "All The Wrong Moves" episode of Kickin' It.
Banned Episode and Bowdlerization: Following complaints from Demi Lovato, the episode "Party It Up" was pulled and later shown edited to remove lines that paint anorexia as a glamorous way to lose weight and not a crippling, psychological disease that both ruins your mind and body.
The Danza: George Lopez as George Martinez, Deuce's father.
Dawson Casting: Roshon Fegan (Ty) is 21 years old and is playing a high schooler. Ainsley Bailey who plays the 15 year old Dina is actually 21.
Playing Against Type: A behind-the-camera case, since the series was created by Chris Thompson - whose previous series (Bosom Buddies, The Naked Truth, Action) are as far away from standard Disney Channel fare as you can get. Especially the last one.
On the other hand perhaps the most famous show he's worked for is Laverne and Shirley. Would go far towards explaining the CeCe/Rocky dynamic.
Screwed by the Network: A lot of people are outright flabbergasted as to why Disney Channel would cancel (or more specifically, fail to order new episodes, with the same effect) their highest-rated show. No official reason has ever been given, but the most believable rumors include Disney Channel felt the show was becoming too expensive and/or simply wanted to move onto new material that would better hold the "next wave" of viewers.
Too Soon: "Shake It Up, Up and Away" was originally scheduled to air on September 18, 2011, but had to be pulled at the last minute due to plane crashes at the Reno Air Show in Nevada. It was replaced with an airing of another new episode that and would air in October, though.
