How many Christmas gift purchases/exchanges/receivings in movies can you think of? The Red Ryder BB gun is a given of course, but don’t forget the “pink nightmare”!
Beyond that, there’s:
Hope and Glory: Older sister gets a ring from her Canadian Army SO, which she rejects (!).
Better Off Dead: “The cutest thing ever…From Roy…A giant. teddy bear. bigger than you. [opens tiny box to reveal miniature teddy bear] Sounds. great…No, no; it really does sound great. Listen, Beth, I gotta go; the Christmas tree’s on fire. [tosses phone]”
Enemy of the State: Will Smith’s character buys lingerie for his wife, and conveniently hangs around in front of the boutique’s security cameras long enough for Jack Black and co. to get a read on him.
Gods and Generals: On Christmas Day, a Union sentry exchanges coffee for a Confederate sentry’s tobacco. They cross a stream to meet in the middle, and for a very tense few minutes, sip and puff while never making eye contact, then nod and return to their sides of the stream.
Hunt for Red October: Jack Ryan flies back to the US with a teddy bear, big enough to need its own seat on the plane (IIRC), for his daughter.
So what else is there?
