Brad Pitt starred in another blockbuster this summer with Bullet Train. The film follows five assassins on a train who discover their missions all have something in common. Bullet Train was a success with audiences and financially, with a 76% audience score on Rotten Tomatoes and a hefty $235 million at the box office against an $86 million budget.

The film is helmed by action enthusiasts David Leitch, responsible for projects such as John Wick, Atomic Blonde, Deadpool 2, and Fast & Furious Presents: Hobbs and Shaw. Joey King, Aaron Taylor-Johnson, Brian Tyree Henry, Andrew Koji, Hiroyuki Sanada, Michael Shannon, and Sandra Bullock star alongside Pitt. Following its successful run at the theater, Bullet Train is preparing for its release in 4K, Blu-ray, and DVD on Oct. 18. DiscussingFilm shared a behind-the-scenes clip featuring Henry and Pitt as a promotion ahead of the release, and the two stars discuss what it was like filming their fight scenes in Bullet Train.

"I was so pleasantly pleased to see this bit of humor designed into the fights," Pitt says. "These guys already had it put together, all we had to do was learn it." Henry goes into further detail, mentioning their fight on the "quiet car" in the film. "I don't know if you've ever had to fight someone for your life, quietly. The choreography, it took me about two weeks to learn this fight." Henry continues, "I'm just gonna tell you, the most distracting part of the fight is Brad's hair. Like he just has this golden wheat, flowy, beautiful Vidal Sassoon f*****g hair. I've never seen anything like it."

Bullet Train featured some of the most original and well-coordinated fights in recent memory. Unlike many movies, the film avoids quick cuts and shaky cameras, with wide angles and longer takes used for the fights. Greg Rementer, second unit director and stunt coordinator behind the film, also shared his take on the quiet car fight scene.

"There has to be acting in the action. Let's talk about something like the Lemon vs. Ladybug fight. They're sitting at a table in a quiet car, that's gold," he explains. "How do you fight while being quiet? So we thought, 'Let's put them in uncomfortable positions so that if she catches them, they have to look buddy-buddy, so instead of just punching punching punching for no reason, we do them in rhythms."

Although Bullet Train is no longer in theaters, fans can still grab the 4K, DVD, and Blu-ray editions later this month on Oct. 18. Of course, due to the first film's success, don't be surprised if Brad Pitt returns for an eventual sequel. But, for now, fans will hope that we get to see more from the Bullet Train universe.
