Corrected entry: In a scene in the last 10 minutes of the movie, the younger sister is coming home from the hospital. She is helped out of a van, into a wheelchair by a few women. When she is pushed up the ramp, a long white cast is on her left leg, in the next scene she is inside the house, in the living room, still in the wheelchair and the cast is now on the right leg. Then in the next scene, she is wheeling herself across the street to her artist friend's house and the cast is back on the left leg again.

Correction: During the "switch" the scene is shown though a mirror (look for the frame), thus the leg cast looks like it's on the opposite leg. The cast is always on the right leg.
