Brad Pitt is an ICON… there’s not debating that.

He’s worked with some of the biggest celebrities and talent in Hollywood. I mean, he is one of the biggest celebrities after all.

However, if you’re new to the acting scene and “set life,” be careful how you act around Mr. Pitt, because he’s watching and taking notes.

Pitt’s “Bullet Train” co-star, Aaron Taylor-Johnson, opened up about working with the Hollywood legend.

Johnson is hoping to stay off of Pitt’s “s**t list.”

Yes, he’s got a running list of s**tty people in the industry that he tries to steer clear of working with.

He went on to explain, “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.”

The U.K. native also took a moment to praise Pitt for being “humble and gracious” to his fellow cast members on “Bullet Train.”
