Los Angeles: Actor Shia LaBeouf, who grabbed headlines because of his erratic behaviour while shooting for his forthcoming movie "Fury", says the recent bouts stemmed from lack of confidence in his own acting abilities.
"I`m not a really confident actor. I don`t have faith in my abilities," theguardian.com quoted the star as saying.
The 28-year-old actor slashed his own face with a knife and got a tooth removed for the war movie "Fury" to get into the character of a war-ravaged soldier.
"It`s like if I told you to react to a gunshot right now. It would be much easier if I just got a gun out and pulled the trigger, because you wouldn`t have to conjure anything. You would just react to it. I try to alter my life so that I don`t have to conjure anything or to make believe," he added.
