Sienna Guillory Joins Cast of CSI
Over the past few weeks, numerous CSI favorites - Jorja Fox, George Eads and Marg Helgenberger most prominently - have renewed their contracts.
But we've got news on a new face coming on board the CBS drama: Sienna Guillory will portray a lab tech named Kacey Monohan.
“We have just started shooting and the atmosphere is electric,” the actress confirmed. “I suggest everyone holds on to their haircuts because my character is going to blow fans away, literally. She’s the team’s first full-time bomb tech and the action scenes will be explosive in every sense.”

Guillory added:
“I jumped at the chance to work alongside producer Jerry Bruckheimer, Laurence [Fishburne, Dr Ray Langston] and the rest of the cast. It’s a dream come true and the only thing that will top this is if they decide to mould a new spin-off show around me. They’d have to call that CSI: Kettering, though, so it might be a stretch.”
CSI returns with new episodes on September 23.

Going by statistics, the vast majority of violent crime in this country is committed by African Americans. Often upon African Americans, Why is this reality not represented in CSI story lines?

Is this the woman that has the world's WORST 'British' accent? She makes me sick.

Terrible idea. Either let her use her real British accent or Americanize her speech. Her fake fashion model accent she is using makes her sound like a bimbo. You have fairly realistic characters now. Why ruin a good thing. Sienna may be a good actress but I'll never know because I can't listen to her. I just shake my head when she is attempting to speak.

I don't know how I feel about her yet. I just can't get over the fact they got rid of Liz! I loved Wendy.

I KNEW she looked familiar!!! I googled her and it turns out she was in one of my favorite movies--ERAGON! She was the princess Arya(hope I spelled it right). She was also in Inkheart, but I didn't see the movie since the book was good but not something I would read again.
