Continuity mistake: The minute hand on the teakettle clock is between the 6 and the 7 when it's shown behind Samantha. When she goes to the closet, the clock reads 8:15 (minute hand on the 3). When she returns, the minute hand is between the 6 and the 7 again.
Continuity mistake: After Samantha sees the statue talking to her, her expression goes from shocked to annoyed and back to shocked in consecutive shots. Also, her hair is over both shoulders in each of the "shocked" shots but over one shoulder in the "annoyed" shot.
