In the beginning of the movie, there is a Christmas party at Josh house. Several minutes into it, Josh, Elizabeth, and Andrew go out on the porch. There is a bit of snowing which stopped after some 15 sec. Some 30 sec later, they all look at the sky and see shooting star. Sky is completely clear and you can see stars! So it seems that snowing just less than a minute ago happened out of nothing as there are no clouds.
The movie takes place in Seattle just before Christmas, and yet you see winter only on stock footage. There are everywhere beautiful green deciduous trees, bushes, and in one scene even flowers which is impossible in December! Production tried to hide it a bit with usage of the artificial snow. Park scene around the third of movie is the most obvious example. Christmas market scene is also full of green trees, and it was obviously warm judging by the clothes on cast and extras. There are multiply extras with just a plain shirt walking in the market.
At 36:19, Josh refers to radio station WZRX, but stations west of the Mississippi River have call signs beginning with K.
