Continuity mistake: When Alice is in Stottlemeyer's office and Stottlemeyer can't find Terry's present, Alice says, "But what about..." indicates the bottle of port, and then drops her arms to her sides. In the next shot (when we see Alice from the back), we can tell by the position of her elbows that her hands are not at her sides, but in front of her.
Continuity mistake: In the beginning scene it shows someone injecting a liquid, with ease, into what appears to be a corked wine bottle. Then around the 13-min mark you see the Captain re-gift the bottle and when the person opens it, it's a pull cork with a hard top, something a needle would not easily go through. (00:00:10 - 00:13:23)
