History Trivia / Sing

-->'''[=McConaughey=]:''' I look back at my last ten years and I haven't made anything my kids can see. It's not a good idea to sit them down in front of a lot...''anything'' in the last ten years ''yet''.

** In the sequel, one of Matthew McConaughey's children voices the piglet that says "this is the greatest day of my life, dad."

* SoMyKidsCanWatch: Matthew [=McConaughey=] made this movie because he realized that his recent body of work was extremely mature and his children couldn't see anything he did.

* CrossDressingVoices: Ms. Crawley is voiced by Creator/GarthJennings, a male actor and the film's director. The same goes in both Mexican and European Spanish dubs, but oddly averted in the Japanese one, when Creator/MayumiTanaka voices her.[[note]]Which is particularly ''ironic'' since she is very well known for voicing boys or male teens, like [[Franchise/DragonBall Krillin]] and [[Franchise/OnePiece Monkey D. Luffy]].[[/note]]
