Brad Pitt and Edward Norton have a close friendship. The two became very tight amid filming and shooting their 1999 cult-classic film, Fight Club.

Cheat Sheet recently recalled one of Pitt's revelations about the film and his friendship with the Hulk actor. He previously shared how they became the "a**holes" at the theater during the premiere of their project.

Speaking to WTF with Marc Maron, the Troy star stated that he and Norton thought "it would be a good idea to smoke a joint" before the premiere. As the movie started, they noticed that the venue was "dead silence" even during the funny scenes.

Brad Pitt continued that it became much "funnier" for him and Edward Norton as the silence persisted. In the end, they were the only ones laughing at their own jokes. The Ad Astra actor, also, admitted that the whole experience with his co-star was, indeed, a "good time."

Months after his revelations, The Things released a report, covering how close Pitt and Norton got during the filming of Fight Club. Speaking to Us Weekly, the 25th hour exclusively shared that there was constant laughter on set.

He added that the whole experience with his co-star, as well as Helena Bonham Carter and the rest of the crew, was an "experience of laughter and creativity." Moreover, he stated that he would love to work with Brad Pitt again in the future.

Apart from the laughs and jokes, the actors were, also, reportedly "comfortable" with each other. Accordingly, this, then, led the World War Z star to a "real punch" from Edward Norton in one of the scenes of their classic film.

Severa rumors even emerged, as well, alleging that Brad Pitt's closeness to Norton caused a strain in the former's marriage to Angelina Jolie. Unnamed sources previously claimed that their usual bonds "angered" the Maleficent actress, making her, reportedly, believe that they should not associate with the Keeping the Faith star.

Alongside Edward Norton, though, Brad Pitt, also, has other close friends in Hollywood. The Talko released a list of his closest links in the industry.

Included in the list are actors Leonardo DiCaprio, Bradley Cooper, George Clooney, Ryan Gosling, and Quentin Tarantino. The likes of Liv Tyler, Julia Roberts, and Margot Robbie are, also, in the roll.

What came as a shock, though, was Jennifer Aniston's inclusion in the list. Based on the publication's report, the former couple is now in a good place as close friends despite their rocky marriage more than a decade ago.
