In "Return to Super Adventure Land", Amy was replaced for the role Gabe's Mom by Gabe's (actual) mom.
A subversion in "The Bob Duncan Experience": During her video diary, Teddy starts to say "When life hands you lemons, make lemonade." This would have been a sly reference to Bridgit Mendler's role as Olivia in Lemonade Mouth, the final scene of which has the saying flashing on video screens behind the band, except that Teddy substitutes "go to the prom with Emmett" for "make lemonade."
Dawson Casting: Most of the actors are older than their characters. Bridgit Mendler is about three years older than Teddy, Jason Dolley is about two years older than PJ, When the show first started, Gabe was supposed to be 10, making Bradley Steven Perry two years older. Amy and Bob were supposed to be high school sweethearts. Leigh Allyn-Baker was 37 when the show first started and Eric Allan Kramer was about 10 years older. Gabe and Charlie are around the same age as their actors portraying them—give or take one year.
Directed by Cast Member: Eric Allan Kramer ("Wentz's Weather Girls" and "Rat-A-Teddy") and Leigh-Allyn Baker ("Charlie Whisperer" and "Bob's Beau-Be-Gone").
Hey, It's That Guy!: There are sure to be plenty of examples, given Disney Channel's tendency to recycle actors as much as possible.
Bridgit Mendler would also go on to do the voice of the main/title character in The Borrower Arrietty. Potentially doubles as an Actor Allusion since her character also has a relationship with David Henrie.
Leigh-Allyn Baker is best known to Disney Channel viewers as Mickey, one of the co-hosts of "The Mack and Mickey Show", a husband and wife-hosted Show Within a Show that featured in two episodes of Hannah Montana. She may also be remembered as Ellen from Willand Grace, or Hannah Webster of Charmed.
Irony as She Is Cast: PJ is dimwitted and a poor guitarist, but Jason Dolley had a 4.0 GPA in high school and is able to play guitar and piano.
Missing Episode: "Down a Tree," the episode featuring the controversial same-sex couple, was skipped in its run in Latin America and Brazil. Oddly enough, the episode was dubbed in Spanish and aired on Disney Channel US's alternate audio track. It wasn't aired in Russia either.
Write Who You Know: In the episode "Return to Super Adventure Land," Gabe says that the mom they got to replace Amy for the commercial looks more like his mom than Amy does. One sure hopes she would - that's Kimberly Perry, Bradley Steven Perry's real-life mom!
Samantha Boscarino (Skyler) has been Bridgit Mendler's best friend since they were 13 (Samantha got Bridgit into the singing and acting business in the first place).
