Michelle Dockery and Matthew McConaughey in The Gentlemen.

There are many reasons to head to the cinema for a showing of Guy Ritchie’s gangster-comedy return, The Gentlemen.

Chief among those reasons is the cast, led by Matthew McConaughey and an extremely amusing Hugh Grant. Throw in Colin Farrell, Charlie Hunnam, Michelle Dockery and Eddie Marsan, all in top form, and you are talking about one of the best casts of the 2020—and it’s only January.

Also, if you are a big fan of weed, you should go see this movie.

The film, directed and co-written by Ritchie, isn’t an amazing piece of scriptwriting. It feels like the other gangster-comedy/drama films he wrote and directed (Snatch and Lock, Stock and Two Smoking Barrels) in that it has zippy dialogue and a fairly routine mystery at its core. However, The Gentlemen is a lot of fun from start to finish, and you will forgive its familiarities and foibles.

McConaughey is at his best as Mickey Pearson, a gangster who has built a large illegal-weed empire as the plant seems headed toward legalization. He’s toying with getting out, and offers his empire to Matthew (Jeremy Strong) for a tidy, semi-reasonable sum. Wife Rosalind (Dockery), a shrewd businessperson, is fine with him retiring—as long as that doesn’t mean he will always be hanging around and bothering her while she’s trying to get stuff done.

However, bodies start piling up as Mickey’s farm locations are getting raided—and somebody in the cast is responsible. That includes Farrell as Coach, a local boxing trainer who has shrewdly constructed a little side game involving street thugs; Ray (Hunnam), Mickey’s right-hand man, who seems loyal but, hey, maybe he’s looking to move ahead in the crime world; and both Lord George (Tom Wu) and Dry Eye (Henry Golding), who have the motive to screw Mickey over because, like Matthew, they want his empire.

Then there’s private-investigator Fletcher (Hugh Grant), who has been following everybody around, gathering evidence to blackmail Mickey—while also writing a screenplay based on the whole mess. Fletcher, in what counts as a framing device, tells Ray his observations throughout the film, and the action plays out along with his storytelling.

Grant gets a chance to act completely sleazy—and it becomes him. Bearded and bespectacled with a full cockney accent, Grant is a crack-up, one of the only real reasons to call this movie a comedy. McConaughey, in contrast, is not a laugh riot; his role combines his laid-back strengths with flashes of full on, brilliant rage. This movie might contain two of my favorite McConaughey-raging moments.

Starting with In Bruges, Farrell moved into my “favorite actors” file and has managed to stay there. His Coach actually feels like an offshoot of his In Bruges persona—with, perhaps, a dash more bravado. His part is smallish, but he makes the most of all his minutes.

Everything plays out in a way that is not surprising, so if you see The Gentlemen looking to judge it on the basis of its mystery contents, you might find yourself disappointed. It’s nothing extraordinary on that front … but it’s not bad, either. When everything is revealed, the results are slightly ho-hum. That doesn’t prevent the film from being an overall good time.

The Gentlemen offers viewers a chance to see a cast having a blast—and to see Ritchie playing in a sandbox that suits him after a slump that included dreck like Aladdin and King Arthur: Legend of the Sword. He’s definitely more at home with snappy, profane dialogue and comic violence than he is with magic carpets and blue genies.

The Gentlemen is playing at theaters across the valley.
