An expletive-laden rant by Batman star Christian Bale on the set of Terminator: Salvation was dismissed as "just a moment that passed" by the film's assistant director.
Bruce Franklin told US entertainment channel E! News that the four-letter tirade was the result of Bale being distracted during an emotional scene.
His rant on set in New Mexico came last July, just days before his arrest by British police investigating claims that he lashed out at his mother and sister in a London hotel.
Clips of the actor shouting at the film's director of photography have been circulating on websites over the last few days.
In the four-minute rant Bale is heard bellowing: "I want you off the set you p****."
The 35-year-old British actor adds that he should "kick his fucking arse".
The apparent cause of the rant was the interruption of photography director Shane Hurlbut during a scene in the making of the latest Terminator movie.
When Mr Hurlbut attempts to apologise, Bale shouts: "Don't just be sorry. Think for one fucking second."
Bale continues: "I'm going to fucking kick your fucking arse.
"Do you want me to trash your lights? Do you want me to fucking trash them?"
Speaking to E! News yesterday, Mr Franklin defended the star.
He said Bale was a "consummate professional" who just had a bad day.
He added: "If you are working in a very intense scene and someone takes you out of your groove - it was the most emotional scene in the movie - and for him to get stopped in the middle of it... He is very intensely involved in his character.
"He doesn't walk around like that all day long. It was just a moment and it passed."
Mr Franklin added: "This was my second movie with Christian, and it has always been a good experience with him.
"He is so dedicated to the craft."
Days after his tirade, Bale was arrested by the Metropolitan Police following an incident involving his mother and sister at the Dorchester Hotel in London on July 21.
The Crown Prosecution Service later decided not to bring charges due to "insufficient evidence to afford a realistic prospect of conviction".
