Earlier today, the paparazzi caught the 57-year-old actor arriving to work on the Damien Chazelle-directed project.
The details of the movie are being kept under wraps.
The film also stars Margot Robbie, Jean Smart and Samara Weaving.
In the snaps, Brad looked quite dapper while wearing a fitted baby blue suit with a pair of classic black Ray-Ban sunglasses. The father of six, who is rocking a mustache for his role, caught the cameraman and flashed a wide smile.
The Ad Astra actor doesn't appear too concerned with Angelina's blossoming romance with The Weeknd. As Radar previously reported, the Eternals actress and the musician were spotted on a third date.
The two were seen leaving the famed Italian restaurant Giorgio Baldi in Santa Monica, Calif. The two arrived separately to the spot but left together after hours inside. Sources close to The Weeknd continue pushing the narrative that the meetings are strictly business.
A source told Page Six, "They’re clearly not trying to hide [the dinner date]. He’s definitely focused on getting to the movie business. He has the new HBO series he’s starring in.”
The pair were first seen together back in July for a dinner date which sparked the initial dating rumors. The dinner also took place at Giorgio Baldi.
At the time, a source told The Sun, "The pair reportedly spent hours at the restaurant, before leaving separately to avoid raising suspicion."
On September 25, the pair had a second dinner date which also took place at the Italian joint.
The Weeknd is the first man Angelina has been seriously linked to since her split from Brad. The actress and her ex-husband are still fighting over the custody of their kids. She scored a huge victory after an appellate court disqualified the judge who awarded her ex-joint custody. Brad is currently asking the court to reconsider the decision to void the custody ruling.
