In Bruges (2008)

I'm a bit surprised that not many people have seen this black comedy.

Two hitmen arrive in Bruges (it's in Belgium) to hide out after doing a job in London.
After checking into their room, the pair go out sight-seeing. Ken (Brendan Gleeson), the older and experienced gangster, loves the cultural and historically-rich city, but Ray (Colin Farrell) appears troubled and can't seem to appreciate the beauty.
Ray finally begins to have fun after meeting a cute production assistant/drug-dealer on a film set when Ken finds out from their boss Harry (Ralph Fiennes) the REAL reason they're in Bruges.

With a compelling, unpredictable plot, the film is mostly dark in tone -- at times, very dark -- and deals with themes of morality, guilt and redemption.
So the laughs aren't in every scene, but when it's funny, it's very funny. Like, how is karate-chopping a dwarf NOT funny?

This is the best acting I've seen from Farrell (probably because he's allowed to be Irish), and Gleeson's character is very likeable. Fiennes, who doesn't appear until later in the story, steals the spotlight to the end of the film as the cussy-mouthed crime boss with resolute principles.

The real star of the film however is the city itself. Shot entirely on location, the cameras go with Ken and Ray as they visit some of the real-life tourist spots; like a chapel that contains a cloth said to contain the blood of Christ; a boat tour on the canal (Bruges is considered the "Venice of the North"); and the Belfry, where some key scenes are set.
The cameras do a good job of capturing the medieval and Gothic architecture.
With the well-preserved architecture, horse-drawn carriages, swans and cobblestone roads, one character remarks, "it's like a fairy tale, isn't it?"
It is, and watching this movie makes me want to visit someday.
