Revealing mistake: When the SWAT team arrive at the house, a member of the team runs towards the house and dives in the snow. However, instead of falling in the snow as you would expect, the white fabric on the floor bunches up.
Revealing mistake: When Clark (on the saucer sled) reaches the bottom of the snow hill, and is on the highway, as the headlights of the truck are coming at him and the "sparks" are flying from under the sled you can see the wheels underneath to make it roll across the highway to reach Walmart's parking lot.
Continuity mistake: The entire Christmas bonus scene at end, Clark's tie changes. Take note of the pattern on the knot, which changes from shot to shot.
Continuity mistake: When Clark is talking to the pretty saleswoman and she says "well, you do have your coat on", he tilts his head down and to his right. In the next shot his head is to his left and he moves it to the right.
Answer: YES! You are 100% correct about the deleted turkey-cooking scene! Both my husband and I remember this scene. It was Catherine and Eddie that cooked the turkey to thank Clark and his family for being hospitable. They had never cooked a turkey before and they thought cooking it at a low temperature for a LONG time would be ideal. It looked great, but completely dehydrated. THIS is why Catherine is so upset when the turkey pops open and steams - she ruined the turkey for everyone.
