Paper Man

Richard's first beer is draft perfect, then the bartender holds a bad beer in his hands.

In the next shot, it is perfect again.

The next shot shows the bad beer again, and then it even dies completely (and there's less beer) in Richard hands, only to be perfect again when he takes his first sip.

From the outside Abby's house has just the second floor with two windows, while in interior scenes Abby lives in an attic with one window.

It also looks much bigger from the inside than from the outside.

Claire closes the car window after Abby approaches her.

In the next shot when she drives away, you can see the window half open (1:33:00).
