Colin Farrell lost his temper with photographers on the red carpet for the premiere of his latest movie at the Toronto Film Festival.

The Irish actor became enraged when the press repeatedly shouted for his sister to move so that they could get a clear shot of the star.

Farrell went nose-to-nose with one photographer, and then quickly regained his composure and went about his business.

The Irishman, who’s been known to lose his cool in the past, was at the international film festival for the premiere of “Triage,” in which he plays a photojournalist suffering from the psychological effects of war.

He arrived at the Elgin Theatre, when photographers began shouting for his entourage to “get off the carpet.”

Farrell then angrily approached London-based Joe Alvarez, who was among those yelling at his companions.

Alvarez has revealed what happened next, saying: “With celebs you get a lot of hangers-on, PRs, everyone and their wives surrounding the stars and we are limited for space.

“I was just saying, 'please can everyone clear the carpet, move on.’

“He took it personal. He said, 'Do not shout at my sister like that, do not ever speak to my sister like that ever.’”

The confrontation quickly died down, and Farrell returned to his spot on the carpet and went on to take his seat in the theatre.

Minutes after the incident, the actor was asked if playing a photojournalist had made him more sympathetic to showbiz photographers.

“It is completely separate,” Farrell said. “I wouldn't ever compare, comparison is a dangerous business.”
