When Matt picks up the milk glasses, he picks his up with his right hand yet gives Alice that glass. A few frames later, both glasses which were only 3 quarters full are now filled almost to the top.
In the very first scene in the shop, Mark Wiebe takes off his ear-phone, puts it in his pocket and turns to Alicia Witt. They kiss, and in the close-up and the next shot his ear-phone is back on.
The kitchen table has slats that run north-south with the Christmas tree placed along the long side. In the "Mitchum Messages" scene, the table is now sideways with the slats running east-west.
When Matt finds Alice at the family home of Will Mitchum, she asks him how he found her. He states that there are only three Mitchums in the town and said that the other "two" were on vacation. That makes four Mitchum residences, not three: two Mitchum families on vacation, his family's home and the home where she is staying.
At :31, as Alice is relaxing under a blanket on the couch, something small (but big enough to be noticeable) mysteriously "scurries" up her left arm, underneath the blanket.
