When Holly pays a surprise daytime visit to her sister, the tree on the snowy front lawn still has fall-colored leaves on its branches.

The movie takes place in Denver, Colorado just before Christmas. Yet right from the start in the first scene in the downtown, you can see a lot of green deciduous trees in windows reflection, and behind Drew's head in close shot. There are also yellowish deciduous trees in the several scenes, too including Apsen selfie scene. And in the most outdoor scene, it can be heard loud bird singing, and singing birds don't sing in December. The only wintery thing is a fake artificial snow. Obviously shot in the late summer and/or early autumn.

Early in the movie, Holly and Drew are sitting down having a conversation at a cocktail party. When the camera is showing a full view of Holly's face, everything lines up perfectly. But when they show Drew head on and you only see the side of Holy's face, her voice and her lip movements are completely out of sync two out of three times in that position.
