Justin Bieber's 'CSI' Story Line Will Be 'Explosive'

He'll play 'a troubled young man ... whose hard-luck life has left him scarred and angry,' executive producer tells MTV News.

With a 3-D movie about his life in the works, fans will get a sneak peek at [artist id="3187077"]Justin Bieber[/artist]'s acting abilities when he makes his network TV acting debut on the "CSI" season premiere next month. It turns out, Justin, a longtime fan of the show, really wanted a part on the series.

"I got a call that Justin really was a fan of 'CSI' [and] that's all I have to hear, and so it just was perfect timing," executive producer Carol Mendelsohn told MTV News about casting the singer in the September 23 episode. "Justin was looking to make his dramatic acting debut. We had an incredible role for a young actor in [our season premiere], so it just seemed like the perfect marriage."

Bieber showed up on set for one day of work, and he managed to impress everyone in the cast with his work ethic. He is part of one very juicy story arc that will likely have viewers coming back later in the season to see what happens next. (Justin shoots again later on in the season for an episode set to air in February.)

"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," she continued. "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."

In a photo tweeted by Bieber, his character is seen handcuffed. So why the cuffs? Well, we got some answers from Mendelsohn.

"He's a troubled young man, raised in the foster-care system, whose hard-luck life has left him scarred and angry," she explained. "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," Mendelsohn teased. "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."
