My point with the milk in the movie is that Thomas Alfredson has a opinion on it, and I am assuming it has some significance. This man ain't right.I'd say "immaturity" is something of a recurrent theme in both the novel and the movie. A lot of the interaction that takes place between the China Restaurant Scooby Gang members could easily have taken place between grade school children.
Does Haken drink milk in the novel? I don't remember. In the movie, he's drinking it in what amounts to a bar; it might be a vague indication of "immaturity", but it could also be taken as a sign the poor man has a sour stomach.
For many people I know personally, there's milk on one side, whiskey on the other and most other beverages somewhere on a line describing something of a spectrum between the two; people who drink milk and fruit juices are "good", people who drink whiskey are "bad", and people who guzzle down grape Nehi have far less "visibly" compromised characters than folks who suck down sixpacks of beer. My coffee habit seems to put me somewhere in the middle.
It could be that Haken drinking milk in a bar is an alcoholic's way of saying "Hi, I'm Haken, and I've been dry for XX days."
In the movie he drinks milk when he is approached by Lacke. In the novel he is drinking distilled spirits. I forget, Lacke buys him a drink? He buys Lacke a drink?
Thomas' interactions with other people are done with a plastic bag over his head, or with the cop in the ICU. Oh, and with Owen. That's about it.
Edit: I checked and in the novel he drinks whiskey and he drinks it "big." Btw, Morgan's joke about cancer makes more sense in the novel's context.
Lacke asks if they should invite Hakan to join their table.
These lines in the movie makes even less sense with Hakan drinking milk. My apologies if anyone has figured this out already. I am just realizing how this all fits together. A forlorn man slams down a big dose of whiskey and attracts the attention of a freeloader. Lacke: what a guy!Morgan glanced at the man, who had sunk together even more. "No, why? What's the use? His wife left him, the cat is dead and life is hell. I know it already.
"Maybe he'll offer to buy us a round."
"That's a different story. Then he's allowed to have cancer as well."
