I had to do Q&As, like, Was it hard working with a child actor?

the writer-director said at a Vulture Festival panel about the film, alongside Norman.
I was like, You have no idea how un-childlike this person is.
And how childish Joaquin [Phoenix] and Gaby [Hoffman] are!
Norman backed Mills up with an example involvingPhoenix, who plays his uncle and guardian.

Its like,Oh!

He is so good.
Mills also remembered the moment: It makes Joaquin fall over, laughing, he said.
