Aaron Taylor-Johnson claims that Pitt has a "good" list and a "s-t" list of people he will and will not work with. 

David Leitch, who directed "John Wick" and "Deadpool 2," directs the pair in "Bullet Train." 

The actor discussed working with Pitt at the Locarno Film Festival in Switzerland, where he was promoting his current film. 

Referring to Pitt as a "humble and gracious individual," the actor told Variety, "I believe he is entering a new phase of his life." 

Taylor-Johnson, who has previously appeared in action films such as "Kick-Ass" and "Avengers: Age of Ultron," stated, "He just wants to bring light and joy into the world and be around people who are there to have a good time."

"You work with many actors and after a while, you start making notes: 'I am definitely not working with this person ever again.' Brad has this list too: the 'good' list and the 's-t' list," he explained.

Taylor-Johnson was hospitalized after sustaining serious injuries while filming a fight sequence in the film, which was released on Friday in the United States. 

After applying a "crazy wild Keto diet" to become "muscular and lean" for the film, the actor fell shortly after suffering a hand injury due to "low blood sugar levels."

"We were in a fight sequence and I get drop-kicked across the room. And the one sharp bit of the corner where there wasn't any padding took a chunk out of my hand. I literally went wham, passed out," he told Variety of the incident.

"Then I came back and was like 'Should we go again?' and they were like 'No, no, no. You gotta go get stitches at the hospital.' So then I spent the night in the hospital," he added.

The actor said that when one is slated to do a David Leitch film, he got to be prepared for some battle scars. 

According to BBC, "Bullet Train" reveals much about Brad Pitt's career to date. As absurd as his codename, Ladybug, Pitt portrays a hitman wearing an unattractive bucket hat. Between fending off assassins on a high-speed Japanese train and attempting to steal a briefcase full of cash, Ladybug is really reciting self-help words in an effort to become a more composed individual.

Pitt states with deadpan accuracy after one violent incident. The outlet also said "Bullet Train" is an action spectacular, but the film's defining characteristic is its sardonic tone, which is shaped and carried by the performance of its lead actor. Upon seeing, one could easily argue that Pitt is an excellent dramatic actor, but an even greater comedic actor.
