When Allison is about to begin baking the cookies for the HUGE Santa Claus party, she sends her daughter off to bed saying, "Goodnight!" It is clearly filmed mid-day, based on the bright sunlight coming through the windows and door, the sun hadn't begun to set. In Tennessee, at Christmas time, sunset would definitely begin by 5pm... It's doubtful that a parent would send their child to bed before 4pm.
The mountain scenes were obviously not shot in eastern Tennessee. Too much snow for it to be Tennessee.
The Smoky Mountains are sometime listed as Smokey Mountains in the movie.
A grandmother in Tennessee is commonly referred to as Mamaw, not granny.
The reporter holds a mic for Channel 10 and call letters KVIW. There is a channel 10 in Knoxville, Tennessee about 30 miles from White Pine, but their letters are WBIR. K is the first letter for stations west of the Mississippi, W for stations east.
There exists no White Pines, Tennessee. There is a White Pine, Tennessee but it has rolling hills but not as mountainous as in the movie. A beautiful place but different.
