In which movie child is so hungry that he cuts out stake picture from magazine and eats paper?

One of the first scenes children plays with marbles (glass beads).
This child has younger brother.
In this memorable eating scene he is staying in apartment but can't go
out because do-not-paid-rent problems or something like that.
After that scene comes his younger brother with food and they are
jumping on the bed with joy. And later comes their father.
