- When Barnum is talking to his daughters about how to improve the show, they suggest "a unicorn or a mermaid". The reply, "Unicorns aren't real" (implying that mermaids are real) is a nod to one of PT Barnum's first attractions: The Fiji Mermaid

There is a scene where Jackman is making a deal with Effron. During this it seems they both drink heavily, but this isn't true, Hugh makes it seem that he is drinking a lot, but he only takes about 2 shots in the entire scene, while he fools Zach into downing about 5.

Barnum uses zebras for his carriage at the beginning when he was proud of the unusual and his "circus freaks". Afterwards when he started to hide his "freaks" and depend on Jenny Lind, he started to use normal horses for his carriage.
