London, Sep 13 - Hollywood actor Colin Farrell was involved in a confrontation with a photographer at the premiere of his new movie 'Triage' Saturday at the Toronto International Film Festival.

The star was attending a screening of his film at the gala event in Canada with his sister and personal assistant Claudine but got high in the head when one snapper Joe Alvarez asked his sibling to step away from her brother's side to allow a clear shot of the 33-year-old actor, reports imdb.com.

Farrell angrily confronted the photographer.

'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',' said Alvarez.
