The A-list pair were spotted on the streets of Los Angeles, head-to-toe in 60s attire, as they worked together shooting a scene in a vintage car.
Brad is pictured in a daring double-denim combo (obviously, 'daring' in this instance translates to 'imagine wearing this without attracting the scorn of your fashionista mates') while Leo looks super slick (credit where it's due) in a vintage-look leather jacket, retro shades and a blinging pinkie ring.
Both are seen sat relaxed in the vintage yellow motor, with Tarantino leaning over giving them direction for the scene.
Set against the backdrop of the infamous Manson Family murders in 1969, the movie will see Brad and Leo play two Hollywood burnouts looking for a way back into the glitz and glamour.
Both characters - a forgotten TV star Rick Dalton (Leo) and his longtime stunt double, Cliff Booth (Brad) - have consistently failed to make it until that fateful night in August 1969, when the Manson Family massacred Rick's next-door neighbour, Sharon Tate.
Manson Family Charles 'Tex' Watson, Susan Atkins and Patricia Krenwinkel butchered Sharon (who was eight-and-a-half months pregnant) at her home in Los Angeles, along with three friends who were visiting at the time. An 18-year-old visitor was also killed as he tried to flee the scene.
The same night, the same Manson Family members also entered the home of grocer Leno LaBianca and murdered him and his wife Rosemary LaBianca.
Charles Manson served a life in prison until his death in November 2017, a week after his 83rd birthday.
The film was initially set for release on 9 August 2019 to coincide with the 50th anniversary of the murders, but has since been brought forward two weeks earlier, after Sharon Tate's sister, Debra, called the original release 'tacky and exploitive'.
The highly anticipated A-list feature will also star Timothy Olyphant, Burt Reynolds, Damian Lewis, Luke Perry, Dakota Fanning, Al Pacino and Margot Robbie as the late Sharon Tate.
