This is marks the second film in which Emily Blunt (The Baker's Wife) and James Corden (The Baker) appear together. The first being Gulliver's Travels (2010). Blunt played a princess while Corden was a servant to the royal family.
According to Anna Kendrick, the set pieces used for the woods were so big and realistic that she and Chris Pine actually got lost while on the sound stage and had to be rescued by a production assistant.
In the original stage play, the baker's father helps his son and his wife with the items they need to lift the curse and dies when it is lifted. In the film, he's only in there after the witch "dies" and the baker leaves the group as a spirit.
When the Baker is talking to his father as he abandons the children, his lips aren't moving throughout the whole conversation. This might, however, be explained by the fact that his father was a hallucination and not actually there.
When the stepmother tosses the pail of lentils into the fireplace, the pail contains barely enough lentils to cover the bottom. When Cinderella and the birds have placed them back inside, the pail is full within a couple of inches of the top. And when Cinderella later presents the pail to her stepmother, it is again not very full.
Jack: [singing]
And you scramble down, and you look below at the world you left, and the things you know. The roof, the house, and your mother at the door.The roof, the house, and the world you'd never thought to explore. And you think of all of the things you'd seen. And you wish that you could live in-between. And you're back again, only different than before.
