16 of the most notorious feuds between actors and directors

• These Hollywood feuds offer a glimpse into the sometimes-fraught world of entertainment.
• From George Clooney and David O. Russell to Katherine Heigl and Judd Apatow, stars can throw punches, literal and figurative, on and off their sets.

• Though some make up after spats, other Hollywood bigwigs never quite get over their friction.

It's no secret that Hollywood can be catty.

Making a film is a stressful experience, and tensions are bound to arise. Many times, the stress of filmmaking comes to a head between lead actors and their directors. 

From name-calling to mind games, from hair-pulling all the way to fist-fighting, notorious actor versus director feuds have been going on for decades.

George Clooney and David O. Russell are said to have physically fought while filming "Three Kings."

Mounting tensions on the set of 1999's "Three Kings" led to a physical fight between the film's star, George Clooney, and its director, David O. Russell.

According to one of the film's producers, Charles Roven, Clooney was tired from working on both "E/R" and "Three Kings" simultaneously, and Russell was experiencing budget pressure from the studio. Allegedly, when Clooney saw Russell yelling at a crew member, it was the final straw. The two engaged in a "tussle," though it's unclear who threw the first hit. 

In a 2000 interview with Playboy, Clooney said Russell's aggression was a widespread problem on set, and that the director also made the script supervisor cry, physically pushed an extra, and embarrassed a camera-car driver. 

Since reports about Harvey Weinstein came out in 2017, stories have surfaced about Russell's on-set abuse.

Roman Polanski allegedly yanked a hair straight out of Faye Dunaway's head on the set of "Chinatown."

Actress Faye Dunaway and famed director Roman Polanski apparently clashed on the set of 1975's "Chinatown."

At one point during filming, Polanski was upset by a stray piece of Dunaway's hair that was ruining his shot, so he walked up to Dunaway and yanked it out of her head. One urban legend says that Polanski's refusal to allow the actress bathroom breaks led to her throwing a cup of her own urine at the director.

Dunaway vehemently denies the urine incident, but has said, "The friction between Roman and me began from the start" of filming.

Director Henri-Georges Clouzot slipped Brigitte Bardot sleeping pills for a scene, and she had to get her stomach pumped.

French director Henri-Georges Clouzot was well-known in the horror genre during the '50s and '60s. While filming "La Vérité" ("The Truth") in 1960, he wanted his lead actress, Brigitte Bardot, to realistically fall asleep and drool for a scene. 

So he apparently gave the actress sleeping pills, claiming that they were painkillers, according to The Guardian. Bardot took too many and ended up having to get her stomach pumped as a result.

After the fact, Bardot infamously called Clouzot "a negative being, for ever at odds with himself and the world around him."

This was just one of many incidents for Clouzot, however, as he reportedly slapped Suzy Delair while filming "Quai des Orfèvres" in 1947.
