I read an unofficial report that said he was doing one of the most emotional scenes in the film and that the person he shouted at had been messing around with his equipment in other scenes of his as well.
He clearly has an anger problem but I want to try and find a defence for his behaviour because I really like him as an actor.
I honestly don't think there is a defence for that kind of abusive behaviour, whatever the situation. I know I might be a bit softly, softly when it comes to arguments etc., but as soon as someone starts using abuse to get their point across, that's when their position in an argument becomes untenable as far as I'm concerned. It's intimidating and just not healthy.
