Justin Bieber CSI behind the scenes pix. More @ J-Bieber.Org. Justin will be honored at Variety's Power of Youth event, Oct. 24 on Paramount's backlot for his commitment to Pencils of Promise, a philanthropic organization that works with local communities to build schools and increase educational opportunities.

CSI executive producer Carol Mendelsohn told MTV News: 'I got a call that Justin really was a fan of 'CSI' [and] that's all I have to hear, it just was perfect timing. Justin was looking to make his dramatic acting debut. We had an incredible role for a young actor, so it just seemed like the perfect marriage.'

There was one day that Justin had available and that was the day he came to 'CSI' and filmed his four scenes for the premiere. We will introduce his character in the premiere in September and then it will be a character arc and we will see him again playing Jason McCann again in February.

He's a troubled young man, raised in the foster-care system, whose hard-luck life has left him scarred and angry. When we first meet Jason, we meet him at a community center where he's giving a testimonial in honor of a man who takes Jason and his older brother in when they had no one else, and that man is now in jail and Jason's brother is out for revenge and looking for payback.

And the CSIs are looking for the brother and Jason is caught in the middle/ At the end of the episode, we're left with the question: Is Jason a good kid stuck in a bad situation or is Jason a bad kid hiding behind his cuteness? You can see why Justin was such a perfect choice to play this role. ..It's an explosive story.'
