WARNING: The following article contains spoilers for Gemini Man, in theaters now.

Gemini Man is a strange film, mixing spy-thriller aesthetics with explosive action between retired assassin Henry Brogan (Will Smith) and a younger clone of him, later revealed to be known as Junior to his surrogate father, Clay (Clive Owen).

While the human elements of the film are mixed and the script is something of a dud, Lee brought all of his action-movie chops to the ambitious project. The film features motorbike chases, gunfights, and someone using the bones of the long-dead to stab a gun. It's kind of great.

Here are the biggest and best action sequences from Gemini Man.

ZAKRZEWSKI'S SKILLS

One of the best small moments in the film occurs early in the narrative, and it doesn't even feature a character played by Will Smith. Instead, it's DIA Agent Zakrzeweski (Mary Elizabeth Winstead) who gets one of the most surprisingly intense fights in the entire movie.

After being alerted to the hit black ops squad sent to take them out, Zakrzeweski prepares to leave alongside Brogan. But one of the agents sneaks up on her with his gun drawn. He threatens to knock out her teeth one at a time if she refuses to tell him where Brogan is. But Zakrzeweski is able to get the drop on him and knock the gun away.

What follows is a close-combat duel between the pair that barrels around the office they're in. The sequence plays out more like a moment from a Bourne film than it does anything else Ang Lee has directed. It's intense in a way most of the rest of the movie isn't.

Zakrzeweski is barely keeping the other agent at bay, trying to wrestle the gun away and avoid being murdered. Unlike Brogan, she's not one of the greatest fighters in the world. The brawl is much more frantic and panicked as a result, and all the more rewarding when she eventually wins the fight, grabs the gun, and proceeds to knock out his teeth until he tells her everything he knows about the black ops team.

For a character who largely stays out of the actual action until the end of the film, Zakrzeweski gets a solid sequence.

BROGAN VS BROGAN: ROUND ONE

The first meeting between Brogan and his younger clone Junior takes place in Columbia. Tracking Brogan down to his friend Baron's (Benedict Wong) home, Brogan is chased around the city by his younger clone. The pair have a tense shoot-out (that includes Junior shooting a grenade in midair to reflect it back at Brogan) before Brogan tries to escape into the city proper. To that end, he ends up stealing a motorbike and carting off.

Junior chases after him, and the scene turns into a fast-paced game of cat and mouse throughout the city. Although Brogan is older and sloppier on the bike than Junior, he's able to use the city to his advantage -- weaving around cars and dodging traffic, at one point even forcing Junior to steal a second bike to keep up. Ultimately though, Brogan ends up on the ground, injured.

Without any more ammo, Junior proceeds to use his bike itself as a weapon, smacking Brogan around and trying to crush him underneath the front wheel. The fight ends up being a draw, however. Although Junior approaches a winded Brogan with a knife, the local police arrive on the scene and force him to flee while Brogan willingly goes into custody to avoid him,.

BROGAN VS BROGAN: ROUND TWO

Their second battle, in the catacombs underneath Budapest, is a much more intense fight. Luring Junior underground with Zakrzewski, he tries to lay a trap for Brogan with Zakrzewski. But using a secret transmitter hidden in her teeth, she's able to keep Brogan informed on Junior's plans. This gives Brogan the chance to set off the traps and trick Junior out of his position, allowing him to get the drop on him and get an assault rifle pointed right at him.

Brogan reveals their connection to Junior, who initially doesn't believe it. He soon breaks free and attacks Brogan. The battle is brutal in a way most of the fights in the rest of the film aren't.

It's different than how Zakarweski dispatched her enemy at the beginning, too. This fight is almost comical in how tough it is on both combatants. While Brogan has the strength to overwhelm Junior, it only gives him an advantage for a while. His experience and tactics give him an early advantage, along with strength enough to briefly overwhelm him.

But Junior's speed and youthful endurance allow him to get the better of Brogan. Using a bone from the tomb as a weapon, Junior is able to wound Brogan before being forced to flee from thanks to Zakrzewski.

WARZONE

After finally coming together, Junior is forced to abandon Brogan and Zakrzewski when a commando team attacks the van carrying them all. Barron is killed in the initial batch of the skirmish, and the two are quickly surrounded. Although they manage to kill many of their enemies, Zakrzewski is wounded and Brogan runs out of ammo. Luckily, Junior returns to help, giving the pair time to respond. But that's when their biggest threat arrives: a third clone of Brogan's, designed without pain receptors or guilt.

This third figure is almost unstoppable, shrugging off bullet wounds and kicks. Both Brogan and Junior working together aren't enough to stop this third clone. Instead, it's Zakrzewski who gives them the advantage.

Getting Brogan and Junior to force the third clone into a corner, Zakrzewski throws an explosive and shoots it just above the third clone. He's quickly consumed in flames. When that fails to stop him, Junior gets hold of the shotgun that the third clone dropped and proceeds to shoot him multiple times.

Finally, this proves too much for him and he drops the clone to the ground. Taking off his helmet, he dies confused, looking at a heartbroken Zakrzewski and not processing why she's so concerned that he can't feel any pain. It gives the (pretty well-constructed fight scene) a surprisingly affecting ending.

In theaters now, Gemini Man is directed by Ang Lee from a script written by David Benioff, Billy Ray and Darren Lemke. The film stars Will Smith, Mary Elizabeth Winstead, Clive Owen, and Benedict Wong.
